M54HC162

M54/74HC160 Decade, Asynchronous Clear M54/74HC161 Binary, Asynchronous Clear M54/74HC162 Decade, Synchronous Clear M54/74HC163 Binary, Synchronous Clear

The M54/74HC160, 161, 162 and 163 are high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERS fabricated with silicon gate C2MOS technology.

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 theM54/74HC161/163 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 CARRYoutput 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
