A D/T edge trigger is a type of digital latch that uses the rising edge of a D-type flip-flop to set the output to a logic 1.
How it works:
When a positive edge pulse is applied to the D input of a D-type flip-flop, the flip-flop's internal logic is reset.
This means that the output is initially set to a logic 0.
When the D input is then set to a logic 1, the flip-flop's internal logic is set to a logic 1.
The output then remains in a logic 1 state as long as the D input is held at a logic 1.
Example:
Consider a D-type flip-flop with input A and output Y. When A is connected to a logic 0 and Y is connected to a logic 1, the flip-flop will trigger and set Y to a logic 1.
Additional notes:
A D/T edge trigger can also be triggered by a negative edge pulse, but it will reset the output to a logic 0.
A D/T edge trigger can be used as a simple latch circuit, or it can be combined with other logic circuits to perform more complex operations.
The D/T edge trigger is a versatile and powerful circuit that can be used in a variety of digital logic applications
