The Tektronix H488 (P/N 155-0178-00,155-0178-05) is a horizontal output amplifier hybrid integrated circuit implemented as a thin-film ceramic hybrid in a custom "Hypcon" package.
It has an input impedance of 50 Ω per side and is designed to operate into a 365 Ω differential load. It has a current gain of 3.3 and is not back terminated.
The device uses T-coils at the input and inductive peaking at the output. Its rise time is approximately 0.5 ns.
It was designed by Dave Morgan and includes D156 transistor dies.
