Inverting Octal 3-STATE Buffer

General Description

The MM74HC240 3-STATE buffer utilizes advanced sili-

con-gate CMOS technology. It possesses high drive cur-

rent outputs which enable high speed operation even when

driving large bus capacitances. These circuits achieve

speeds comparable to low power Schottky devices, while

retaining the advantage of CMOS circuitry, i.e., high noise

immunity and low power consumption. It has a fanout of 15

LS-TTL equivalent inputs.

The MM74HC240 is an inverting buffer and has two active

LOW enables (1G and 2G). Each enable independently

controls 4 buffers.

All inputs are protected from damage due to static dis-

charge by diodes to V
