DESCRIPTION

The M54/74HC423/423A are high speed CMOS MONOSTABLE multivibrators fabricated with silicon gate C2MOS technology.

They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

■ HIGH SPEED

tPD = 25 ns (TYP) at VCC = 5V

■ LOW POWER DISSIPATION

STANDBYSTATE ICC=4 µA (MAX.) AT TA=25°C

ACTIVESTATE ICC =700µA (MAX.)AT VCC=5V

■ 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
