These small chips were 18 or 24 pins? The beauty of this simple circuit is it actually debounces your switch, i. Dec 242: Synthesized tuning, Part 2: Therefore almost every post I write would usually be updated several times till it reaches its saturation: The switches are given to each participating competitors and the respective bulbs can be placed before them to determine which team pressed the switch first.

It doesnt latch in HIGH state. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time.

Similar for other switch input. PV charger battery circuit 4. Do I need pull up resistors or does this sound like bad chips.

IC 74LS373, TTL LS series, OCTAL D-TYPE TRANSPARENT LATCHES AND EDGE-TRIGGERED FLIP-FLOPS, DIP20

If you have CD, the remaining 2 gates can be used to combine the 2 switches in one. This low state in the LE pin enables the latch of the IC thereby providing continuous high signal in the output pin.

Hierarchical block is unconnected 3. Problem with 74LS latching!

It could have been a useful touch switch which weren’t very common thenbut I learnt how to filter out, clamp and provide 774ls373 instead! The led in the circuit is always Off. How reliable is it? Originally Posted by kripacharya.

Any other idea is also welcomed. I have 5V on D, but only get 3.

I mean which part of circuit is troubling you?

Input port and 47ls373 output port declaration in top module 2. SCR Silicon Controlled rectifier was connected to the output pins of the IC and along with it diodes are also connected. Also I may not reply at time. You have LE fixed High, hence output equals input Datasheet of 74LS is also attached.
