The 74HC04 inverters utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with low power consumption of standard CMOS integrated circuits.The MM74HC04 is a triple-buffered inverter. It has high noise immunity and the ability to drive 10 LS-TTL loads. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
Typical propagation delay: 8ns
Fan out of 10 LS-TTL loads
Quiescent power consumption: 10uW maximum at room temperature
