DESCRIPTION
The DG417L/418L/419L are low voltage pin-for-pin
compatible companion devices to the industry standard
DG417/418/419 with improved performance
Combining high speed (tON: 28 ns), flat rON over the analog
signal range (6 ꢀ ), minimal insertion lose (up to 100 MHz),
and excellent crosstalk and off-isolation performance (-70 dB
at 1 MHz), the DG417L/418L/419L are ideally suited for audio
and video signal switching.
Using BiCMOS wafer fabrication technology allows the
DG417L/418L/419L 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 DG417L and DG418L respond to opposite control logic as
shown in the Truth Table. The DG419L has an SPDT
configuration.
