This circuit is from documentation from 1965 but can be easily implemented today using modern transistors. We can use BD136 for Q1 and TIP42 for Q2. The TIP must be equipped with a heat sink.
This circuit can be used in fiber optic links or even direct links to microcontrollers and other...
Suggested by Hughes in 1968 documentation, this circuit makes use of a transistor matched pair and...
This 600-ohm line driver was found in a 1980s documentation. The integrated circuit used is not...
