The ISL59442 is a single-output 4:1 MUX-amp.
The MUX-amp has a fixed gain of 1 and a 1GHz bandwidth.
The device contains logic inputs for channel selection (S0, S1), and a three-state output control (HIZ) for individual selection of MUX amps that share a common video output line.
All logic inputs have pull-downs to ground and may be left floating.
