- Isolated Full-duplex Serial Interface
- Level Meter Circuits SPM-3 WG
The 555 Astable generates a clock for this circuit, an oscillator giving a square wave output at pin 3 which is counted by 4017 to give a running lights effect.
I would like to build Optoisolated RS232 interface. I’vesearched a little bit, and I came across your design:
RS232 with Opto-Isolation
However presented schematic is of poor quality – I’m not able to read all parts numbers and their values.
Here are three circuits from the manual. The design is entirely on discrete devices like transistors, diodes and zeners. Studying these designs will reinforce your basics.

- LF398 – Monolithic Sample and Hold Circuit
This is an old article from Practical Electronics 1979. It shows the input circuits and digital ranging controls too. Using 7107 chip for display it is an excellent project to build even today.
There is a long gap between engineering college and mid career in a non-engineering position, but technology marches on so a simple method of keeping abreast with the latest developments is required.
The LF198/LF298/LF398 are monolithic sample-and-hold circuits which utilize BI-FET technology to obtain ultra-high dc accuracy with fast acquisition of signal and low droop rate.
