The TC74HC240A, 241A and 244A are high speed CMOS

OCTAL BUS BUFFERs fabricated with silicon gate C2MOS

technology.

They achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The 74HC240A is an inverting 3-state buffer having two

active-low output enables. The TC74HC241A and TC74HC244A

are non-inverting 3-state buffers that differ only in that the 241A

has one active-high and one active-low output enable, and the

244A has two active-low output enables.

These devices are designed to be used with 3-state memory

address drivers, etc.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features

• Output drive capability: 15 LSTTL loads

• Pin and function compatible with 74LS240/241/244
