DESCRIPTION
The M74HC163 is an high speed CMOS
SYNCHRONOUS 4 BIT BINARY PRESETTABLE
COUNTER fabricated with silicon gate C²MOS
technology.
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 synchronous to the

CLOCK. 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.
