The input NAND stage converts the two D input states (0 and 1) to these two input combinations for the next SR latch by inverting the data input signal. The low state of the enable signal produces the inactive "11" combination. Thus a gated D-latch may be considered as a one-input synchronous SR latch. This configuration prevents application of ...

A 555 timer can act as an active-low SR latch (though without an inverted Q output) with two outputs: output pin is a push-pull output, discharge pin is an open-collector output (requires a pull-up resistor). For the schematic on the right, a Reset input signal connects to the RESET pin and connecting a Set input signal to the TR pin.

When the input is below a different (lower) chosen threshold the output is low, and when the input is between the two levels the output retains its value. This dual threshold action is called hysteresis and implies that the Schmitt trigger possesses memory and can act as a bistable multivibrator (latch or flip-flop). There is a close relation ...

First introduce the SR latch. Next introduce the clocked SR latch (i.e., SR latch with AND gates in front and a "clock" input). Next introduce the edge-triggered SR flip flop. Next introduce the edge-triggered JK flip flop. Add combinational logic to describe D and T flip flops.
