MM74C192 MM74C193
Synchronous 4-Bit Up/Down Decade Counter
Synchronous 4-Bit Up/Down Binary Counter
General Description
The MM74C192 and MM74C193 up/down counters are
monolithic complementary MOS (CMOS) integrated cir-
cuits. The MM74C192 is a BCD counter, while the
MM74C193 is a binary counter.
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
external circuitry.
