PIN CONNECTIONS (top view)
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 simi-
lar 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 counter-
s.
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 ris-
ing edge of the CLOCK.
The function on the M54/74HC162/163 is syn-
chronous 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 volt-
age.
