The TC74VHC245 is an advanced high speed CMOS OCTAL

BUS TRANSCEIVER fabricated with silicon gate C2MOS

technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low

power dissipation.

It is 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.
