DESCRIPTION

The M74HC279 is an high speed CMOS QUAD S - R LATCH fabricated with silicon gate C2MOS technology.

■ HIGH SPEED:

tPD = 13ns (TYP.) at VCC = 6V

■ LOW POWER DISSIPATION:

ICC =2µA(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 279
