The CD74HC04E is a CMOS logic high-speed Hex Inverter, this logic gate utilizes silicon-gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. This device has the ability to drive 10 LSTTL loads. The 74HCT logic family functionally is pin compatible with the standard 74LS logic family.
Buffered inputs
Balanced propagation delay and transition times
Significant power reduction compared to LSTTL logic ICs
