DESCRIPTION
The M54/74HC242/243 are high speed CMOS

technology. They have the same high speed
performance of LSTTL combined with true CMOS
low power consumption. The HC242/243 are 3
STATE bi-directional inverting and non-inverting
buffersandare intended for two-way asynchronous
communication between data buses. They are high
drive current outputs which enable high speed
operation when driving large bus capacitances.
Each device hasone active high enable (GBA), and
one active low enable (GAB). GBA enables the A
outputs and GAB enables the B outputs. All inputs
are equipped with protection circuits against static
discharge and transient excess voltage.
