DESCRIPTION

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
