General Description
MARKING DIAGRAMS
The MM74HC240 3−STATE buffer utilizes advanced silicon−gate
CMOS technology. It possesses high drive current 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 discharge by
