MM74C193 - Synchronous 4-Bit Up/Down Binary Counter

Download the MM74C193 datasheet PDF. This datasheet also covers the MM74C192 variant, as both devices belong to the same synchronous 4-bit up/down binary counter family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • s High noise margin: 1V guaranteed s Tenth power TTL compatible: Drive 2 LPTTL loads s Wide sup.

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”.
