Overview

TC74VHC245F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC245F, TC74VHC245FK Octal Bus Transceiver 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.
