The Tektronix 155-0154-00 (M154) is a Tek-made display multiplexer in a 20-pin DIP, designed by Harvey Golladay.
It transmits one of three sets of 2-channel (X, Y) inputs (hardcopy, alphanumeric mode or vector mode) selected by 2 input bits (A, B).
A counter sequences through eight offset positions each time a "page" (erase) signal is received.
These offsets are added to the X and Y inputs to uniformly exercise the phosphor on all parts of the screen.
