Each 4-bit counter is increases during the high to

low transition (negative edge) of the clock input,

and each has an independent clear input. When

CLEAR is set to low, all four bits of each counter

are set to a low level. This enables count

truncation and allows the implementation of divide

by N counter configurations.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

DESCRIPTION

The M54HC393 is an high speed CMOS DUAL

BINARY COUNTER fabricated with silicon gate

C MOS technology.

This counter circuit contains independent ripple

carry counters and two 4-bit ripple carry binary
