This is SYNCRONOUS UP/DOWN DECADE accomplished by inputting a high on the CLEAR COUNTERS fabricated with silicon gate C2MOS input. All 4 internal stages are set to low technology. independently of either COUNT input. Both a The counter has two separate clock inputs, an UP BORROW and CARRY output are provided to COUNT input and a DOWN COUNT input. All enable cascading of both up and down counting outputs of the flip-flop are simultaneously functions. The BORROW output produces a triggered on the low to high transition of either negative going pulse when the counter underflows clock while the other input is held high. The and the CARRY outputs a pulse when the direction of counting is determined by which input counters overflows. The counter can be cascaded is clocked. This counter may be preset by entering
