The IN74HCU04A is identical in pinout to the LS/ALS04. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

This device consists of six single-stage inverters. These inverters are well suited for use as oscillators, pulse shapers, and in many other applications requiring a high-input impedance amplifier. For digital applications, the HC04 is recommended.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V; 2.5 to 6 V in Oscillator Configurations.

• Low Input Current: 1.0 mA

• High Noise Immunity Characteristic of CMOS Devices
