DESCRIPTION

The M54/74HC4078 is a high speed CMOS 8 INPUT NOR/OR GATE fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

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

■ HIGH SPEED

tPD = 13 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 4078B
