DESCRIPTION
The DG9424/9425/9426 are low voltage precision monolithic
quad single-pole-single-throw analog switches.
Using BiCMOS wafer fabrication technology allows the
DG9424/9425/9426 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.
Combining high speed (t
ON
: 42 ns), flat r
DS(on)
over the analog
signal range (
W
), minimal insertion lose (-3 dB at 190 MHz),
and excellent crosstalk and off-isolation performance, the
DG9424/9425/9426 are ideally suited for audio and video
signal switching.
The DG9424 and DG9425 respond to opposite control logic as
shown in the Truth Table. The DG9426 has two normally open
and two normally closed switches.
