DESCRIPTION
The M74HC4078 is an high speed CMOS 8-INPUT NOR/OR GATE fabricated with silicon gate C2MOS technology.
   
■ HIGH SPEED:
    tPD = 10ns (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 4078
