DESCRIPTION

The M54/74HCT02 is a high speed CMOS QUAD 2-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 gives high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED tPD = 11 ns (TYP.) AT VCC = 5 V

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

■ COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX)

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

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

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS02
