Description

These TRI-STATE bidirectional inverting and non-inverting buffers MM74HC242 utilize advanced silicon-gate CMOS technology and are intended for two-way asynchronous communication between data buses. They have high drive current outputs which enable high speed operation when driving large bus capacitances. These circuits possess the low power dissipation and high noise immunity associated with CMOS circuits, but speeds comparable to low power Schottky TTL circuits. MM74HC242 can also drive 15 LS-TTL loads.

The MM54HC243/MM74HC243 is a non-inverting buffer and the MM54HC242/MM74HC242 is an inverting buffer. Each device has one active high enable (GBA), and one active low enable (GAB). GBA enables the A outputs and GAB enables the B outputs. This device does not have Schmitt trigger inputs.

All inputs of MM74HC242 are protected from damage due to static discharge by diodes to VCC and ground.
