74VHCT245

Octal Bidirectional Transceiver with 3-STATE Outputs

General Description

The VHC/VHCT245 is an advanced high speed CMOS octal

bus transceiver fabricated with silicon gate CMOS technol-

ogy. It achieves high speed operation similar to equivalent

Bipolar 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 de-

vice so that the busses are effectively isolated. All inputs are

equipped with protection circuits against static discharge.

Features

High Speed:

VHC t

= 4.0 ns (typ) at V

= 5V

VHCT t

= 5.3 ns (typ) at V

= 5V

High Noise Immunity:

VHC V

NIH

= V

NIL

= 28% V

(Min)

VHCT V

= 2.0V, V

= 0.8V

Power Down Protection:

VHC Inputs Only

VHCT Inputs and Outputs

Low Noise:

VHC V

OLP

= 0.9V (typ)

VHCT V

OLP

= 1.1V (typ)

Low Power Dissipation:

= 4 µA (Max)

= 25˚C
