Product Summary

The HC244 is an Octal 3-state noninverting buffer/Line driver/line receiver which is identical in pinout to the LS/ALS244. The HC244 inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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.
