HC244中文资料SLS数据手册PDF规格书

The SL74HC244 is identical in pinout to the LS/ALS244. The device 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.

· Outputs Directly Interface to CMOS, NMOS, and TTL

· Operating Voltage Range: 2.0 to 6.0 V

· Low Input Current: 1.0 mA
