MM74HC240
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
CC
and ground.
