High–Performance Silicon–Gate CMOS
The MC54/74HC244A is identical in pinout to the LS244. 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
bus–oriented systems. The device has noninverting outputs and two
active–low output enables.
The HC244A is similar in function to the HC240A and HC241A.
• 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: 136 FETs or 34 Equivalent Gates
