They have the same the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The M54/74HC160/162 are BCD Decade counters and the M54/74HC161/163 are 4 bit binary counters.
The CLOCK input is active on the rising edge.
Both LOAD and CLEAR inputs are active Low.
Presetting of all four IC’s is synchronous on the rising edge of the CLOCK.
The function on the M54/74HC162/163 is synchronous to CLOCK, while the M54/74HC160/161 counters are 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.
