MM74C193 counter equivalent, synchronous 4-bit up/down binary counter.
s High noise margin: 1V guaranteed s Tenth power TTL compatible: Drive 2 LPTTL loads s Wide sup.
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 h.
