A . latch. is a temporary storage device that has two stable states (bistable). It is a basic form of memory. . The S-R (Set-Reset) latch is the most basic type. It can be constructed from NOR gates or NAND gates. With NOR gates, the latch responds to active-HIGH inputs; with NAND gates, it responds to active-LOW inputs.. © 2014 Project Lead The Way, Inc..

Combinational Logic versus Sequential Logic. A . combinational logic circuit. is a circuit whose output depends only on the circuit’s present inputs. (“Has no memory of the past.”). Register is built with gates, but has memory.. The only type of flip-flop required in this class – the D flip-flop . Has at least two inputs (both 1-bit): D and . clk. Has at least one output (1-bit): Q. Chapter 5. Sequential Circuits. Combinational circuits storage (store binary information). Binary information stored defines the state of the sequential circuit. External input present state determine the binary value of outputs and change state in storage elements. Sequential Circuits. Moris. . Mano. 4. th. . Ediditon. Revision. Types of Logic Circuits.
