The M54/74HC7245 HC7640, HC7643 and HC7645 utilise silicon gate C2MOS technology to achive operating speeds equivalent to LSTTL devices. Along with the low power dissipation and high noise 2 immunity of standads C MOS integrated circuit, it possesses the capability to drive 15 LSTTL loads. These IC's are intended for two-way asynchronous communication between data buses, and the direction of data trasmission is determined by DIR input. The enable input (G) can be used to disable the device so that the buses are effectively isolated. The HC7245/640/7643/7645 have the same pin PIN CONNECTION (top view)
HC7640 HC7643
configuration and function as the HC245/640/643 and they have a hysteresis characteristics with each input, so HC7245/7640/7643/7645 can be used as a line receiver, etc. All input are equipped with protection circuits against static discharge and transient excess voltage. IT IS PROHIBITED TO APPLY A SIGNAL TO A BUS TERMINAL WHEN IT IS IN OUTPUT MODE AND WHEN A BUS THERMINAL IS FLOATING (HIGH IMPEDANCE STATE), IT IS REQUESTED TO FIX THE INPUT LEVEL BY MEANS OF EXTERNAL PULL DOWN OR PULL UP RESISTOR.
HC7645/HC7245
HC7245 is electrically and funcutionally the same as the HC7645
