155-0064-00

The 155-0064-00 is a custom IC hybrid developed by Tektronix in the early 1970's, primarily as a vertical output amplifier for oscilloscopes.

It is packaged in a 12-pin TO-8 stud mounted can. Maximum power dissipation is 4 watts. The rise time is specified as 470 ps (equiv. bandwidth 745 MHz).

The hybrid consists of three dice: the M080 differential amplifier ("f_t doubler"), and two D078 NPN output transistors in common-base configuration.
