MM74C192 Datasheet (Fairchild) - Synchronous 4-Bit Up/Down Decade Counter

MM74C192, Synchronous 4-Bit Up/Down Decade Counter

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.
