The Tektronix M020F  (P/N 155-0015-00,155-0015-01) is an analog data switch monolithic integrated circuit for the 7000 series readout system in a 16-pin DIP, designed by Barrie Gilbert.

It accepts nine inputs at currents from 0 to 1 mA and selects one under the control of a BCD code. The output is from an NPN collector. The inputs are virtual grounds within ±100 mV of ground potential for the input range of ±1 mA.

Besides the use in the readout system the 155-0015-0X is also used as the Z-axis data switch for the autofocus system in many 7000 mainframes.
