DESCRIPTION

The

M54HC160

is

an

high

speed

CMOS

SYNCHRONOUS

BCD

DECADE

PRESETTABLE COUNTER fabricated with silicon

The CLOCK input is active on the rising edge.

Both LOAD and CLEAR inputs are active LOW.

Presetting is synchronous on the rising edge of

the clock, the function is cleared asynchronously.

Two enable inputs (TE and PE) and CARRY

output are provided to enable easy cascading of

counters, which facilities easy implementation of

N-bit counters without using external gates.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
