Overview

MM74C192 • MM74C193 Synchronous 4-Bit Up/Down Decade Counter • Synchronous 4-Bit Up/Down Binary Counter January 1991 Revised October 1999 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 circuits.
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.
