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
