M74HCT04 Hex inverter Features High speed: t = 11 ns (typ.) at V =4.5 V PD CC Low power dissipation: I = 1 A (max.) at T =25 C CC A DIP-14 Compatible with TTL outputs: V = 2 V (min.) V = 0.8 V (max) IH IL Balanced propagation delays: t t PLH PHL Symmetrical output impedance: SO-14 I = I = 4 mA (min) OH OL Pin and function compatible with 74 series 04 Description The M74HCT04 is a high speed CMOS hex 2 inverter fabricated with silicon gate C MOS 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 2 HSC MOS systems with TTL and NMOS components. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
