DESCRIPTION

The M54/74HC390 is a high speed CMOS DUAL
DECADE COUNTER fabricated in silicon gate
C2MOStechnology.It hasthesamehighspeedper­formance of LSTTL combined with true CMOS low
powerconsumption.

Thisdualdecade counter containstwo independent
ripple carry counters. Each counter is composed of
a divide-by-two and divide-by-five counter. The
divide-by-two and divide-by-five counters can be
cascaded to form dual decade, dual biquinary, or
various combinations up to a single divide-by-100
counter.

Each4-bit counter is incremented onthe hightolow
transition (negative edge) of the clock input, and
eachhas an independent clear input. When clearis
set low all four bits of each counter are set to low.
This enables count truncation and allows the im­plementation of divide-by-N counterconfigurations.

All inputs are equipped with protection circuits
against static discharge and transient excess volt­age.
