MM54C192/MM74C192

Synchronous 4-Bit Up/Down Decade Counter

MM54C193/MM74C193

Synchronous 4-Bit Up/Down Binary Counter

General Description

Features

High noise margin

1V guaranteed

Drive 2 LPTTL loads

3V to 15V

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.

Tenth power TTL compatible

Wide supply range

Carry and borrow outputs for N-bit cascading

Asynchronous clear

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.

High noise immunity

0.45 V (typ.)

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.
