) at VCC = 6V LOW POWER DISSIPATION: ICC = 1µA(MAX.
) at TA=25°C HIGH NOISE IMMUNITY: VNIH = V NIL = 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 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HC51B1R M74HC51M1R T&R M74HC51RM13TR M74HC51TTR 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.
