DESCRIPTION

The M54/74HC4002 is a high speed CMOS DUAL 4-INPUT NOR GATE fabricated in silicon gate C2MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption. The internal circuit is composed of 3 stages including buffer output, which ensures high noise immunity and stable output.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED tPD = 10 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 1 µA (MAX.) AT TA = 25° C

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 4002B
