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

Features

■ High noise margin: 1V guaranteed

■ Tenth power TTL compatible: Drive 2 LPTTL loads

■ Wide supply range: 3V to 15V

monolithic complementary MOS (CMOS) integrated cir-

cuits. The MM74C192 is

a BCD counter, while the

MM74C193 is a binary counter.

■ 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_CC(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

external circuitry.
