When the two inputs are low, then the output of Y0 is logic 1 and the other outputs are logic 0. If both the inputs are high, then the output of Y3 is logic 1 and the other output pins are logic 0.

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”.

WebbShift registers come in two basic types, either SIPO, Serial-In-Parallel-Out, or PISO, Parallel-In-Serial-Out. SparkFun carries both types. Here is a SIPO, the 74HC595, and the PISO, the 74HC165.
