DESCRIPTION

The M54/74HC4022 is a high speed CMOSOCTAL COUNTER/DIVIDER fabricated in silicon gate C2MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

■ HIGH SPEED

fMAX = 57 MHz (TYP.) at VCC = 5 V

■ LOW POWER DISSIPATION

ICC 4 ?A (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 4022B
