High–Performance Silicon–Gate CMOS
The MC54/74HC240A is identical in pinout to the LS240. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
This octal noninverting buffer/line driver/line receiver is designed to be
used with 3–state memory address drivers, clock drivers, and other
sub–oriented systems. The device has inverting outputs and two active–low
output enables.
The HC240A is similar in function to the HC241A and HC244A.
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1
