M74HCT04 Hex inverter Features ■ ■ ■ ■ ■ ■ High speed: tPD = 11 ns (typ.) at VCC = 4.5 V Low power dissipation: ICC = 1 μA (max.) at TA = 25 °C Compatible with TTL outputs: VIH = 2 V (min.) VIL = 0.8 V (max) Balanced propagation delays: tPLH tPHL Symmetrical output impedance: |IOH| = IOL = 4 mA (min) Pin and function compatible with 74 series 04 SO-14 DIP-14 Description The M74HCT04 is a high speed CMOS hex inverter fabricated with silicon gate C2MOS technology. The internal circuit is composed of 3 stages including a buffer output, which enables high noise immunity and stable output. The M74HCT04 is designed to directly interface HSC2MOS systems with TTL and NMOS components. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
