The figure below shows the logic circuit of an SR latch. In the above logic circuit if S = 1 and R = 0, Q becomes 1. Let us explain how. NOR gate always gives output 0 when at least one of the inputs is 1. So when S is applied as 1 the output of gate G2 i.e. is 0 ...
To understand the working of SR NAND latch, we need to have a look at the truth table of NAND gate given below. Case 1: When S=0, R=0 Let us suppose, the value of Q at the start of the circuit be 1, then inputs at the lower gate will be 1, thus from truth table of NAND...
SR-LatchFlip-FlopA low voltage and low power SR-latch based flip-flop design is proposed. It is adapted from a classic text-book-style all-NAND based flip-flop design and achieves circuit simplification by eliminating redundant logic. The optimization measure leads to a new design featuring ...
A NAND gate with seven inputs is required. For each of the following cases, minimize the number of gates used in the multiple-level result: a. Design the 7-input NAND gate using 2-input NAND gates and What is the main use of an emitter follower circuit?
If both the values of S and R are switched to 1, then the circuit remembers the value of S and R in their previous state. Clocked S-R Flip Flop It is also called a Gated S-R flip flop. The problems with S-R flip flops using NOR and NAND gate is the invalid state. This proble...
An input priority determination circuit is configured such that: (i) when a set signal S is asserted and a reset signal R is negated, an intermediate set signal S′ is asserted and a
The S-R flip-flop is a single-bit data storage circuit that can be constructed using basic gates. Adding gate enable circuitry to the S-R flip-flop makes it synchronous. This means that it will operate only under the control of a clock or enable signal. ...
In addition, the output of AND gate 156 will be low thereby opening drain valve 95 anytime any one of switches S2-S11 are not selected (low on L72) or when the circuit is reset on reset 90 which is applied through an inverter 180 to reset latches 162A and 162B. The novel ...
