DESCRIPTION

The DG1411E, DG1412E, DG1413E are ± 15 V precision

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

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

Siliconix DG1411E, DG1412E, and DG1413E 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 do not 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 DG1411E, DG1412E, and DG1413E 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 DG1411E is

normally closed, while the DG1412E is normally open. The

DG1413E has two normally open and two normally closed

switches with guaranteed break-before-make operation.

Combined with fast 70 ns switching time, low and flat switch

resistance. The devices are 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.
