DESCRIPTION
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 C
2
MOS
technology.
They have the same the high speed operation simi-
lar to equivalent LSTTL while maintaining the
CMOS low powerdissipation.
The M54/74HC160/162 are BCD Decade counters
and theM54/74HC161/163 are4 bitbinary counter-
s.
The CLOCK input is active on the rising edge. Both
LOADand 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 CARRYoutput
are provided to enable easy cascading of counters,
which facilities easy implementation
counters without using external gates.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
