Abstract
A high speed voltage switching circuit comprises symmetrically arranged voltage relay transistor circuits coupled between voltage input terminals and a switched voltage output terminal. A first voltage relay transistor circuit relays a first voltage at the first input terminal to the output terminal in response to the controlled application of current directly to the output terminal from a first switched current source. A second voltage relay transistor circuit relays a second voltage at the second input terminal directly to the output terminal in response to the removal of current from the output terminal by way of a second switched current source. Each voltage relay transistor circuit preferably comprises pairs of bipolar transistors having their base-emitter junctions coupled in series between the first voltage input terminal and the output terminal. To prevent reverse application of the high and low voltages to the voltage input terminals of the switching circuit, a reverse voltage protection circuit is coupled between the first and second voltage relay transistor circuits.
