DESCRIPTION

The M74HC21 is an high speed CMOS DUAL 4-INPUT AND GATE fabricated with silicon gate C2MOS technology.

The internal circuit is composed of 3 stages 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 21
