DESCRIPTION

The DG441L, DG442L are low voltage pin-for-pin

compatible companion devices to the industry standard

DG441L, DG442L with improved performance.

Using BiCMOS wafer fabrication technology allows the

DG441L, DG442L to operate on single and dual supplies.

Single supply voltage ranges from 3 V to 12 V while dual

supply operation is recommended with ± 3 V to ± 6 V.

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, DG442L are

ideally suited for audio and video signal switching.

The DG441L, DG442L responds to opposite control logic as

shown in the Truth Table open and two normally closed

switches.
