DESCRIPTION

The DG9424/9425/9426 are low voltage precision monolithic

quad single-pole-single-throw analog switches.

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.

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.
