MC74HC244A: Octal 3-State Non-Inverting Buffer/Line Driver/Line Receiver

Description: High-Performance Silicon-Gate CMOS

The MC7...
  • 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.
