MM54C192 MM74C192
Synchronous 4-Bit Up Down Decade Counter
MM54C193 MM74C193
Synchronous 4-Bit Up Down Binary Counter
General Description
These up down counters are monolithic complementary
MOS (CMOS) integrated circuits The MM54C192 and
MM74C192 are BCD counters while the MM54C193 and
MM74C193 are binary counters
Counting up and counting down is performed by two count
inputs one being held high while the other is clocked The
outputs change on the positive-going transition of this clock
These counters feature preset inputs that are set when load
is a logical ‘‘0’’ and a clear which forces all outputs to ‘‘0’’
when it is at a logical ‘‘1’’ The counters also have carry and
borrow outputs so that they can be cascaded using no ex-
ternal circuitry

Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
