DESCRIPTION
The M54/74HC390 is a high speed CMOS DUAL
DECADE COUNTER fabricated in silicon gate
C
2
MOStechnology.Ithas thesame highspeedper-
formance of LSTTL combined with true CMOS low
powerconsumption.
Thisdualdecade counter contains twoindependent
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.
Each 4-bit counter isincremented on thehightolow
transition (negative edge) of the clock input, and
each has an independent clear input. When clear is
set low all four bits of each counter are set to low.
This enables count truncation and allows the im-
plementation of divide-by-N counter configurations.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
