CD40192BM/CD40192BC Synchronous

4-Bit Up/Down Decade Counter

CD40193BM/CD40193BC Synchronous

4-Bit Up/Down Binary Counter

General Description

Features

Wide supply voltage range

3V to 15V

0.45 V (typ.)

These up/down counters are monolithic complementary

MOS (CMOS) integrated circuits. The CD40192BM and

CD40192BC are BCD counters, while the CD40193BM and

CD40193BC are binary counters.

High noise immunity

Low power TTL compatibility

Fan out of 2

driving 74L

or 1 driving 74LS

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.

Carry and borrow outputs for easy expansion to N-bit

by cascading

Asynchronous clear

These counters feature preset inputs that are enabled when

load is a logical ‘‘0’’ and a clear which forces all outputs to

‘‘0’’ when it is at logical ‘‘1’’. The counters also have carry

and borrow outputs so that they can be cascaded using no

external circuitry.

Equivalent to

MM54C192/MM74C192

and MM54C193/MM74C193

All inputs are protected against damage due to static dis-

charge by clamps to V

and V
