MC74VHCT240A

Octal Bus Buffer/Line Driver

Inverting with 3−State Outputs

The MC74VHCT240A is an advanced high speed CMOS octal bus

buffer fabricated with silicon gate CMOS technology. It achieves high

speed operation similar to equivalent Bipolar Schottky TTL while

maintaining CMOS low power dissipation.

The MC74VHCT240A is an inverting 3−state buffer, and has two

active−low output enables. This device is designed to be used with

3−state memory address drivers, etc.

The VHCT inputs are compatible with TTL levels. This device can

be used as a level converter for interfacing 3.3 V to 5.0 V, because it

has full 5.0 V CMOS level output swings.

The VHCT240A input and output (when disabled) structures

provide protection when voltages between 0 V and 5.5 V are applied,

regardless of the supply voltage. These input and output structures

help prevent device destruction caused by supply

voltage−input/output voltage mismatch, battery backup, hot insertion,

etc.

Features

• High Speed: tPD = 5.6 ns (Typ) at VCC = 5.0 V

• TTL−Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V

• Power Down Protection Provided on Inputs and Outputs

• Balanced Propagation Delays

• Designed for 4.5 V to 5.5 V Operating Range

• Low Noise: VOLP = 1.1 V (Max)

• Pin and Function Compatible with Other Standard Logic Families

• Latchup Performance Exceeds 300 mA

• ESD Performance:

Human Body Model > 2000 V;

Machine Model > 200 V

• Chip Complexity: 110 FETs or 27.5 Equivalent Gates

• These Devices are Pb−Free and are RoHS Compliant
