155-0022-00

The Tektronix 155-0022-00 (M036) is a Tek-made analog multiplexer chip in a 16-pin DIP, designed by Gene Andrews It was made for many years and was eventually replaced by the 234-0408-20.

It is used to multiplex between the two vertical plug-ins and also to switch trigger sources.

Tek expected the 155-0022-00 to have a yearly failure rate of 0.05%.
