MC74HC244A
Octal 3âState Noninverting
Buffer/Line Driver/
Line Receiver
HighâPerformance SiliconâGate 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 3âstate memory address drivers, clock drivers, and
other busâoriented systems. The device has noninverting outputs and
two activeâlow output enables.
The HC244A is similar in function to the HC240A.
Features
⢠Output Drive Capability: 15 LSTTL Loads
⢠Outputs Directly Interface to CMOS, NMOS, and TTL
⢠Operating Voltage Range: 2.0 to 6.0 V
⢠Low Input Current: 1 mA
⢠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
⢠PbâFree Packages are Available*
