MC100E131FN

Logic - Flip Flops

MC100E131FN is a high performance CMOS logic device of ECLL family from ON Semiconductor. It is one kind of flip flop circuits, also known as SR flip flop, and it contains two inputs and two outputs. Its two inputs, set (S) and reset (R), will take the outputs T and Q to two different states. Its response time is extremely fast and is ideal for high performance clock circuit applications.

Application Field

MC100E131FN can be used in a variety of applications, such as data transmission, logic families, and circuits. Its most popular application is to be used as a data latch in order to store data; it is also used as a master-slave type synchronous sequential circuit, where the logic state of a data bit is determined by the logic state of its present and previous inputs. In addition, its S and R inputs can be used to select one of the two outputs, T or Q, that is needed in the application.

Working Principle

The MC100E131FN has two inputs and two outputs, S and R, as well as T and Q. When the input S is active (high logic levels), the output T is activated and Q is deactivated, and the output state is said to be ‘set’ in this condition. Conversely, when the input R is activated, the output T is deactivated and Q is activated, and the output state is said to be ‘reset’ in this condition. The MC100E131FN is also able to store the input logic level, as any logic change in the S or R input will not affect the output until both inputs become inactive (low logic levels).

Additionally, the MC100E131FN utilizes Schmitt triggers at the inputs, which ensure precise, switch debouncing and glitch-free input transitions. This helps to ensure that the output is not affected by any momentary voltage fluctuations, or transient noise, which could lead to incorrect output logic levels.
