Overview
TECHNICAL DATA IN74HCT244A Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The IN74HCT244A is identical in pinout to the LS/ALS244.
The device may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs.
The IN74HCT244A is an octal noninverting buffer/line driver/line receiver designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems.
The device has non-inverted outputs and two active-low output enables.
• TTL/NMOS-Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 4.
5 to 5.
5 V • Low Input Current: 1.
