General Description
The MM74C192 and MM74C193 up/down counters are
monolithic complementary MOS (CMOS) integrated circuits. The MM74C192 is a BCD counter, while the
MM74C193 is a binary counter.
Counting up and counting do wn is pe rform ed by tw o count
inputs, one being hel d hig h whil e the other is cloc ked. T he
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 o utputs to
“0” when it is at a logical “1”. The counter s also have car ry
and borrow outputs so th at t hey can be cascaded using no
external circuitry.
Features
■ High noise margin: 1V guaranteed
■ Tenth power TTL compatible: Drive 2 LPTTL loads
■ Wide supply range: 3V to 15V
■ Carry and borrow outputs for N-bit cascading
■ Asynchronous clear
■ High noise immunity: 0.45 V
