DESCRIPTION The M54HC163 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.
