Overview

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 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 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
  • Pb-Free Packages are Available*
