MC74AC646, MC74ACT646 Octal Transceiver/Register with 3-State Outputs (Non-inverting)The MC74AC646/74ACT646 consist of registered bus transceiver circuits, with outputs, D–type flip–flops and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data on the A or B bus will be loaded into the respective registers on the LOW–to–HIGH transition of the appropriate clock pin (CAB or CBA). The four fundamental data handling functions available are illustrated Figures 1 to 4.•Independent Registers for A and B Buses•Multiplexed Real–Time and Stored Data Transfers •Choice of True and Inverting Data Paths•3–State Outputs•300 mil Slim Dual In–Line Package•Outputs Source/Sink 24 mA•′ACT646 Has TTL Compatible InputsREAL TIME TRANSFERAĆBUS TO BĆBUSREAL TIME TRANSFERDevice Package ShippingORDERING INFORMATIONMC74AC646N PDIP–2415 Units/Rail MC74AC646DW SOIC–2430 Units/Rail MC74ACT646N PDIP–2415 Units/RailMC74AC646DWR2SOIC–241000 T ape & Reel MC74ACT646DW SOIC–2430 Units/Rail MC74ACT646DWR2SOIC–241000 T ape & ReelPIN ASSIGNMENTFigure 6.

Both busses are capable of sinking 64 mA, have 3-STATE outputs, and a common output enable pin. The direction of data flow is determined by the transmit/receive (T/R) input. The 74F645 is a high speed/low power version of the 74F245. The 74F640 is an inverting option of the 74F645.Featuress Designed for asynchronous two-way data flow between busses s Outputs sink 64 mAs Transmit/receive (T/R) input controls the direction of data flow s 74F645 is a lower power, faster version of the 74F245s 74F640 is an inverting option of the 74F645Ordering Code:Devices also available in T ape and Reel.

If the device is dis-abled (OE HIGH), the outputs are in the high impedance state. The transmit/receive input (T/R) controls whether data is transmitted from the A bus to the B bus or from the B bus to the A bus. When T/R is LOW, B data is sent to the A bus. If T/R is HIGH, A data is sent to the B bus.Function TableH = HIGH Voltage Level L = LOW Voltage Level X = Don’t CareZ = High Impedance StateLogic Diagram74F64074F645Pin Names DescriptionU.L.Input I IH /I IL HIGH/LOW Output I OH /I OL OE Output Enable Input (Active LOW) 1.0/1.020 µA/−0.6 mA T/R Transmit/Receive Input 1.0/1.020 µA/−0.6 mA A 0–A 7Side A Inputs or 3.5/0.66770 µA/−0.4 mA 3-STATE Outputs 600/106.6−12 mA/64 mA B 0–B 7Side B Inputs or 3.5/0.66770 µA/−0.4 mA 3-STATE Outputs600/106.6−12 mA/64 mAInputs OutputsOE T/R 74F64074F645L L Bus B data to Bus A Bus B data to Bus A L H Bus A data to Bus BBus A data to Bus BHXZZ74F640 • 74F645Absolute Maximum Ratings (Note 1)Recommended Operating ConditionsNote 1: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired.

TI is not responsible or liable for any such statements.Buyer acknowledges and agrees that it is solely responsible for compliance with all legal,regulatory and safety-related requirements concerning its products,and any use of TI components in its applications,notwithstanding any applications-related information or support that may be provided by TI.Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures,monitor failures and their consequences,lessen the likelihood of failures that might cause harm and take appropriate remedial actions.Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.In some cases,TI components may be promoted specifically to facilitate safety-related applications.With such components,TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements.Nonetheless,such components are subject to these terms.No TI components are authorized for use in FDA Class III(or similar life-critical medical equipment)unless authorized officers of the parties have executed a special agreement specifically governing such use.Only those TI components which TI has specifically designated as military grade or“enhanced plastic”are designed and intended for use in military/aerospace applications or environments.Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk,and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.TI has specifically designated certain components which meet ISO/TS16949requirements,mainly for automotive ponents which have not been so designated are neither designed nor intended for automotive use;and TI will not be responsible for any failure of such components to meet such requirements.Products ApplicationsAudio /audio Automotive and Transportation /automotiveAmplifiers Communications and Telecom /communicationsData Converters Computers and Peripherals /computersDLP®Products Consumer Electronics /consumer-appsDSP Energy and Lighting /energyClocks and Timers /clocks Industrial /industrialInterface Medical /medicalLogic Security /securityPower Mgmt Space,Avionics and Defense /space-avionics-defense Microcontrollers Video and Imaging /videoRFID OMAP Mobile Processors /omap TI E2E Community Wireless Connectivity /wirelessconnectivityMailing Address:Texas Instruments,Post Office Box655303,Dallas,Texas75265Copyright©2012,Texas Instruments Incorporated。
常用74系列芯片特性分类及中文名称资料
ALS TTL 10 -15/64
LS TTL 18 -15/24
LVC
AC
S
LC
说明：
1）LS是低功耗肖特基，HC是高速COMS；LS的速度比HC略快，HCT输入输出与LS兼容，但是功耗低；F是高速肖特基电路；
2）LS是TTL电平，HC是COMS电平；
3）LS输入开路为高电平，HC输入不允许开路，HC一般都要求有上下拉电阻来确定输入端无效时的电平，LS 却没有这个要求；
4）LS输出下拉强上拉弱，HC上拉下拉相同；
5）工作电压不同：LS只能用5V，而HC一般为2V到6V；
6）电平不同：LS是TTL电平，其低电平和高电平分别为0.8和V2.4，而CMOS在工作电压为5V时分别为0.3V和3.6V，所以CMOS可以驱动TTL，但反过来是不行；

DescriptionThese devices consist of bus transceiver circuits with TRI-STATE D-type flip-flops and control circuitry arranged formultiplexed transmission of data directly from the input busor from the internal registers Data on the A or B bus will beclocked into the registers as the appropriate clock pin goesto a high logic level Control G and direction pins are provid-ed to control the transceiver function In the transceivermode data present at the high impedance port may bestored in either the A or the B register or in both The selectcontrols can multiplex stored and real-time(transparentmode)data The direction control determines which bus willreceive data when the enable control G is Active LOW Inthe isolation mode(control G HIGH) A data may be storedin the B register and or B data may be stored in the A regis-terFeaturesY Independent registers for A and B busesY Multiplexed real-time and stored dataY’F648has inverting data pathsY’F646 ’F646B have
