WebbThe output at Q remains at HIGH or at logic level “1” as one of its inputs is still at logic level “0”. As a result, there is no change in state. Therefore, the flip-flop circuit is said to be “LATCHED” or “SET” with Q = 1 and Ǭ = 0. The Reset State In this second stable state, Q is at logic level ‘0” and its inverse output Q is at logic level “1”.

Webb27 aug. 2007 · or a gate or a complete circuit can also be called as active high or active low. If just first statement is true than it is simple.we can say that the input which gives high output when the input is low is called active low input and that one which gives high output at high input is called active high. WebbThe 3-state output buffers are designed to drive heavily loaded 3-state buses, MOS memories, or MOS microprocessors. The active low output enable (n OE) controls all ten 3-state buffers independent of the register operation. When n OE is LOW, the data in the register appears at the outputs.
