One article understands full view of chip of logic of holy state microelectronics

Regard those who execute basic and logistic function as yuan of parts of an apparatus, standard logic parts of an apparatus and heavy and complicated of sort of range of products of logic of low power comsumption, application is wide. Industry of chip of imitate of profit from deep ploughing is accumulated for years, holy state microelectronics is in logistic the domain has kind of chip quite whole product position and extensive client group, can offer include drive of register of logistic door, trigger, Suo Cunqi, shift, bumper, line, bus line to send and receive implement, voltage n changeover is sent and receive implement the extensive logic range of products that waits inside and the technique that match to it and solution.

Logistic door

Door circuit is the basic and logistic unit of digital circuit, basically use at coming true to be mixed basically commonly used logistic operation. Our for instance most familiar 3 kinds of basic and logistic doors — with the door (AND) , or the door (OR) with blame door (NOT) . Be based on these 3 kinds of logistic doors, still can derive relatively complex with blame door (NAND) , or blame door (NOR) etc. The product basically divides the logistic door circuit of holy state microelectronics to wait for a type for Single-Gate, Dual-Gate, Quad-Gate, Hex-Gate, Multiple-Function Gate, have very excellent performance is enclosed with what abound, can satisfy requirement of each differentia dissimilation.

Trigger

Trigger is to form sequential logic circuit and the basic and logistic unit of all sorts of complex number systems. Trigger can pass the one or more signal that brings to bear on to input end in control to change the position of oneself, can have 1 or many output, it is the computer, communication and the main component of subsystem of report of the number in a lot of other type systems.

It is with 74LVC74 exemple, this is one has set and restoration function edge sparks D trigger, acceptability 1.2V comes limits of voltage of 3.6V broad power supply, its are installed and restoration dispute synchronism is inputted (low n is effective) , clock inputs OK and independent operation; 74LVTN16374 is trigger of 16 D edge, 2.7V of limits of power source voltage comes 3.6V, 3 condition are outputted, can provide the capability of drive high electric capacity or load of relatively low impedance, suit to be used at realizing driver of port of amortize register, I/O, two-way bus line and working register.

Suo Cunqi

Suo Cunqi is had 0 with two 1 steady state, once condition is decided, can maintain by oneself, put n change till the lock, just change position, this kind of character can be used at buy is entered and storing data of a binary system. Compare with trigger photograph, n sparks Suo Cunqi, edge sparks trigger.

Holy state microelectronics has 8 to mix 16 at present two kinds of big Suo Cunqi. 74LVCN16373 is a 16 D that have 3 state output transparent Suo Cunqi, can use at 1.2V to be operated to 3.6V power supply, for every Suo Cunqi offers independent D input, offer 3 state output to face the application of bus line.

Shift register

In digital circuit, shift register is a kind of is a foundation with trigger parts of an apparatus that works below same time pulse. Data arrives with input of collateral or serial means in parts of an apparatus, every time pulse is ordinal move backward a bit, undertake finally outputting in output end. Register of this kind of shift is one dimension, still have multidimensional shift register in fact, namely the data itself of input, output is a few. The shift register parallel connection that has a few identical digit rises can realize this kind multidimensional shift register.

74AHC595 is the input of travel of 8 bit string that a belt outputs Suo Cunqi / serial output or register of collateral output shift, have serial input and the serial standard output that are used at cascade. 8 register are in make can when have asynchronous restoration function.

Drive of bumper, line and bus line are sent and receive implement

Drive of bumper, line and bus line are sent and receive implement main effect is integrality of the signal in enhancing a system. Microelectronics of state of emperor of have the aid of is much paragraph product, the user can solve common drive intensity low with circuit capacitance advanced problem.

74AHC244Q is an octal bumper that has 3 state output / line drive. This chip can use as two 4 bumper or 8 bumper, 5.5V of voltage of the biggest input. This character makes parts of an apparatus OK use as in mixture voltage environment converter. In addition, this driver passed AEC-Q100 attestation, apply to car application.

Voltage n changeover is sent and receive implement

Voltage n changeover is sent and receive implement or logistic n changeover is sent and receive implement product, basically use at resolving the tension between region of different power source incompatible problem.

74AVCH2T45 is changeover of n of a voltage of 2 double power source is sent and receive implement, can mix in 0.8V, 1.2V, 1.5V, 1.8V, 2.5V 3.3V voltage node is changed between any medium voltage node, suit to break electric application partly, cut off the power when equipment namely when, can prevent facility of electric regurgitate inpour.

74AVC4T245Q is changeover of n of a voltage of 4 double power source is sent and receive implement, have 3 state output and two-way n transition, can use as two 2 changeover are sent and receive implement or 4 changeover are sent and receive implement. As similar as 74AVCH2T45 is, this parts of an apparatus also suits to apply at cutting off the power partly to apply setting very much; Different point depends on, 74AVC4T245Q passed AEC-Q100 attestation, apply to car application.

Epilogue

Overall and character, standard logic solution emphasizes using gender and flexibility easily more in design application, to hold the lead position in logistic market, besides small-sized enclose, capability of low power comsumption, low voltage, drive is strong the development that waits for innovation technology, still include to offer the commitment that long lifecycle sustains to the client. In the meantime, union can be accelerated and simplify the of all kinds resource that develops the work, not only can simplify design, still can help an user accelerate process of products introducing to the market.
