74VHC245 Octal Bidirectional Transceiver with 3-STATE Outputs

November 1992

Revised April 2005

74VHC245

Octal Bidirectional Transceiver with 3-STATE Outputs

General Description

The VHC245 is an advanced high speed CMOS octal bus

transceiver fabricated with silicon gate CMOS technology.

It achieves high speed operation similar to equivalent Bipo-

lar Schottky TTL while maintaining the CMOS low power

dissipation. The VHC245 is intended for bidirectional asyn-

chronous communication between data busses. The direc-

tion of data transmission is determined by the level of the

T/R input. The enable input can be used to disable the

device so that the busses are effectively isolated. All inputs

are equipped with protection circuits against static dis-

charge.
