PIN CONNECTIONS (top view)

The M54/74HCT160, 161, 162 and 163 are high

speed CMOS SYNCHRONOUS PRESETTABLE

COUNTERS fabricated with silicon gate C²MOS

technology. They have the same high speed oper-

ation similar to equivalent LSTTL while maintaining

the CMOS low power dissipation.

The M54/74HCT160/162 are BCD Decade counter-

s and the M54/74HCT161/163 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 ris-

ing edge of the CLOCK. The function on the

M54/74HCT162/163 is synchronous to CLOCK,

while the M54/74HCT160/161 counters are cleared

asynchronously. Two enable inputs (TE and PE)

and CARRY output are providedto enable easycas-

cading of counters, which facilities easy implemen-

tationof N-bit counters without using external gates.

This integrated circuit has input and output charac-

teristics that are fully compatible with 54/74 LSTTL

logic families. M54/74HCT devices are designed to

directly interface HSC²MOS systems with TTL and

NMOS components. They are also plug in replace-

ments for LSTTL devices giving a reduction of

power consumption. All inputs are equipped with
