The M74HC51 is an high speed CMOS DUAL 2 WIDE 2 INPUT AND/OR INVERT GATE fabricated with silicon gate C2MOS technology. It contains a 2-WIDE 2-INPUT AND/OR INVERT GATE and a 2-WIDE 3-INPUT AND/OR INVERT GATE.
The internal circuit is composed of 3 stages (2 INPUT) or 5 stages (3 INPUT) including buffer output, which enables high noise immunity and stable output.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
■ HIGH SPEED: tPD = 11ns (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 % VCC (MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH = tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 51
