M74HC4022 OCTAL COUNTER/DIVIDER

The M54/74HC4022 is a high speed CMOS OCTAL COUNTER/DIVIDER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It contains a 4-stage divide-by-8 Johnson counter with 8 decoded outputs (Q0-Q7) and a Carry-out bit.

. HIGH SPEED fMAX = 57 MHz (TYP.) at VCC = 5 V . LOW POWER DISSIPATION ICC 4 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 4022B M54HC4022 M74HC4022 OCTAL COUNTER/DIVIDER B1R (Plastic Package) F1R (Ceramic Package) M 1R (Micro Package) .
