MM54C192/MM74C192 Synchronous 4-Bit Up/Down Decade Counter, MM54C193/MM74C193 Synchronous 4-Bit Up/Down Binary Counter

General Description\nThese up/down counters are monolithic complementary MOS (CMOS) integrated circuits. The MM54C192 and MM74C192 are BCD counters, while the MM54C193 and MM74C193 are binary counters.\nCounting up and counting down is performed by two count inputs, one being held high while the oth High noise margin 1V guaranteed\nTenth power TTL compatible Drive 2 LPTTL loads\nWide supply range 3V to 15V\nCarry and borrow outputs for N-bit cascading\nAsynchronous clear\nHigh noise immunity 0.45 VCC (typ.);
