DESCRIPTION
The DG441L/442L are low voltage pin-for-pin compatible
companion devices to the industry standard DG441L/442L
with improved performance
Combining high speed (tON: 20 ns), flat rDS(on) over the analog
signal range (5 ꢀ ), minimal insertion lose (-3 dB at 280 MHz),
and excellent crosstalk and off-isolation performance (-50 dB
at 50 MHz), the DG441L/442L are ideally suited for audio and
video signal switching.
Using BiCMOS wafer fabrication technology allows the
DG441L/442L to operate on single and dual supplies. Single
supply voltage ranges from 3 to 12 V while dual supply
operation is recommended with "3 to "6 V.
The DG441L/442L responds to opposite control logic as
shown in the Truth Table. open and two normally closed
switches.
