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 DG9421/9422 combine low and flat on-resistance
(3
W),
fast speed (t
ON
= 38 ns) and low charge injection (less
than 1 pC) and is well 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.
