The SL74HC11 is identical in pinout to the LS/ALS11. The device inputs are comp atible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

● Outputs Directly Interface to CMOS, NMOS, and TTL
● Operating Voltage Range: 2.0 to 6.0 V
● Low Input Current: 1.0 mA
● High Noise Immunity Characteristic of CMOS Devices
