SEMICONDUCTOR TECHNICAL DATA
Octal 3-State Noninverting
Buffer/Line Driver/
Line Receiver
High–Performance Silicon–Gate CMOS
The MC54/74HC241A is identical in pinout to the LS241. 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 noninverted outputs and two output
enables. Enable A is active–low and Enable B is active–high.
The HC241A is similar in function to the HC244A and HC240A.
• 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 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 134 FETs or 33.5 Equivalent Gates
