Octal 3-State Non-Inverting Buffer/Line Driver/Line Receiver
----High–Performance Silicon–Gate CMOS
The MC74HC244A 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. Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating V oltage 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
