General Description
The MM74HC04 inverters utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with the 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.

FEATUREs
■ Typical propagation delay: 8 ns
■ Fan out of 10 LS-TTL loads
■ Quiescent power consumption: 10 µW maximum at room temperature
■ Low input current: 1 µA maximum
