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 www.DataSheet4U.com 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. Features s High noise margin: 1V guaranteed Drive 2 LPTTL loads s Tenth power TTL compatible: s Wide supply range: 3V to 15V s Carry and borrow outputs for N-bit cascading s Asynchronous clear s High noise immunity: 0.45 VCC (typ.)
