Meaning that i want to trigger the timer, allow it to enable output HIGH (charge cycle) and then on discharge cycle output will be LOW, but trigger must not be allowed to trigger timer till discharge cycle is over. WebDec 16, 2024 · Working Explanation. This simple latch circuit can be operated using a 5V-12 battery. The circuit uses two transistors. One is an NPN 2N4401 transistor named Q1. Other is a PNP 2n4403 transistor named Q2. When a signal or a pulse is applied at the base of the Q1, the Q1 starts conducting and thus connects the base of the Q2 to the ground, as a ...

WebMar 26, 2016 · Then, the latch inputs will be operational only when the 555 timer’s output is HIGH. Note that the ENABLE input is often called the CLOCK input. You can easily add an ENABLE input to a latch by adding a pair of NAND gates. Here, the SET and RESET inputs (SR latch) are connected to one input of each of the two NAND gates. WebQuestion 18. Gated latch circuits often come packaged in multiple quantities, with common gate inputs, so that more than one of the latches within the integrated circuit will be enabled and disabled simultaneously.
