DESCRIPTION

Using BiCMOS wafer fabrication technology allows the

DG9421, DG9422 to operate on single and dual supplies.

Designed for optimal performance at single 5 V and dual

± 5 V, the DG9421, DG9422 combine low and flat

on-resistance (3

Ω), fast speed (t

suited for applications where signal switching accuracy, low

noise and low distortion is critical.

The DG9421 and DG9422 respond to opposite control logic

as shown in the Truth Table.
