DESCRIPTION

The M54/74HC4022 isa 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.

It contains a 4-stage divide-by-8 Johnson counter

with 8 decoded outputs (Q0-Q7) and a Carry-out bit.

This counter is advanced on the positive edge of the

clock signal when CLOCK ENABLE input is held

low, or is advanced on the negative edge of clock

enable signal when CLOCK input is held high, and

the selected one of eight outputs goes high.Holding

the CLEAR input high clears the counter to zero re-

gardless of the other input conditions. All inputs are

equipped with protection circuits against static dis-

charge and transient excess voltage.

NC =

No Internal
