Webdiode is often required for standard TTL one-shots to pre-vent high inverse leakage current. This switching diode is not needed for the ’LS123 one-shot and should not be used. In general the use of the switching diode is not recommended with retriggerable operation. Furthermore, if a polarized timing capacitor is used on the WebTo solve this problem, we use different ICs that come inverters, the 74LS04 is one of the best IC of 74LS series to use as a transistor. ... 74LS04 gives the output in TTL logic, …
