SEMICONDUCTOR TECHNICAL DATA

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.

DW SUFFIX

20–LEAD SOIC PACKAGE

CASE 751D–04

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.
