A gated SR latch circuit diagram constructed from AND gates (on left) and NOR gates (on right) A gated SR latch can be made by adding a second level of NAND gates to an inverted SR latch. The extra NAND gates further invert the inputs so a SR latch becomes a gated SR latch (a SR latch would transform into a gated SR latch with inverted enable).
An NMOS NAND gate with saturated enhancement-mode load device. The enhancement device can also be used with a more positive gate bias in a non-saturated configuration, which is more power efficient but requires a high gate voltage and a longer transistor. Neither is as power efficient or compact as a depletion load.
Its fast transistor-level implementation is used in the semistatic C-element proposed. [52] Yet another semistatic circuit using pass transistors (actually MUX 2:1) has been proposed. [53] Yet another version of the C-element built on two SR-latches has been synthesized by Murphy [54] using Petrify tool. However, this circuit includes inverter ...
A CMOS transistor NAND element. V dd denotes positive voltage.. In CMOS logic, if both of the A and B inputs are high, then both the NMOS transistors (bottom half of the diagram) will conduct, neither of the PMOS transistors (top half) will conduct, and a conductive path will be established between the output and Vss (ground), bringing the output low.
"A synchronous SR latch (sometimes clocked SR flip-flop) can be made by adding a second level of NAND gates to the inverted SR latch (or a second level of NOR gates to the direct SR latch)." The description does not match the circuit shown below. There are no NAND gates anywhere. A gated SR latch circuit diagram constructed from NOR gates.

The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
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 between the two kinds of circuits: a Schmitt trigger can be converted into a latch and a latch can be converted into a Schmitt trigger.
