DESCRIPTION

The M54/74HC4022 isa highspeedCMOSOCTAL
COUNTER/DIVIDER fabricated in silicon gate
C2MOS technology.

It has the same high speed performance of LSTTL
combined withtrue CMOSlowpower consumption.
It contains a 4-stage divide-by-8 Johnson counter
with8 decodedoutputs(Q0-Q7)andaCarry-outbit.
Thiscounterisadvanced onthepositive edge ofthe
clock signal when CLOCK ENABLE input is held
low, or is advanced on the negative edge of clock
enable signalwhen CLOCKinput is held high, and
the selectedoneof eightoutputsgoes high.Holding
the CLEAR inputhigh clearsthe counter to zerore­gardless of the other input conditions. All inputsare
equipped with protection circuits against static dis­charge andtransientexcess voltage.
