The TC74HC245A, 640A are high speed CMOS OCTAL BUS

TRANSCEIVERs fabricated with silicon gate C2MOS technology.

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

They are intended for two-way asynchronous communication

between data busses. The direction of data transmission is

determined by the level of the DIR input.

The enable input ( G ) can be used to disable the device so that

the busses are effectively isolated.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Wide operating voltage range: V

(opr) = 2~6 V

Pin and function compatible with 74LS245/640

Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.

Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull

down resistors.
