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.

Input Capacitance Power Dissipation Capacitance (note 1)
1) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
TEST CIRCUIT
