MC74VHC240

Octal Bus Buffer/Line Driver

Inverting with 3-State Outputs

The MC74VHC240 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 MC74VHC240 is an inverting 3−state buffer, and has two

active−low output enables. This device is designed to drive bus lines

or buffer memory address registers.

MARKING

DIAGRAMS

The internal circuit is composed of three stages, including a buffer

output which provides high noise immunity and stable output. The

inputs tolerate voltages up to 7V, allowing the interface of 5V systems

to 3V systems.
