DESCRIPTION

The DG1411, DG1412, DG1413 are ± 15 V precision

monolithic quad single-pole single-throw (SPST) CMOS

analog switches. Built on a new CMOS process, the Vishay

Siliconix DG1411, DG1412, and DG1413 offer low

on-resistance of 1.5 ?. The low and flat resistance over the

full signal range ensures excellent linearity and low signal

distortion. The new CMOS platform provides low power

dissipation, minimized parasitic capacitance, and low

charge injection.

The devices operate from either a single 4.5 V to 24 V power

supply, or from dual ± 4.5 V to ± 15 V power supplies. The

analog switches don't require a VL logic supply, while all

digital inputs have 0.8 V and 2 V logic thresholds to ensure

low-voltage TTL / CMOS compatibility.

The DG1411, DG1412, and DG1413 are bi-directional and

support analog signals up to the supply voltage when on,

and block them when off. The devices each feature four

independently selectable SPST switches. The DG1411 is

normally closed, while the DG1412 is normally open. The

DG1413 has two normally open and two normally closed

switches with guaranteed break-before-make operation.

Combined with fast 100 ns switching times, the improved

performance of the DG1411, DG1412, and DG1413 make

the devices ideal for signal switching and relay replacement

in data acquisition, industrial control and automation,

communication, and A/V systems, in addition to medical

instrumentation and automated test equipment.

The switches are available in RoHS-compliant, halogen-free

TSSOP16 and QFN16 4 mm by 4 mm packages.
