DG441B

Improved Quad SPST CMOS Analog Switches

Vishay Semiconductors 

DG441B, DG442B

Vishay Siliconix

Improved Quad SPST CMOS Analog Switches

DESCRIPTION

The DG441B, DG442B are monolithic quad analog switches

designed to provide high speed, low error switching of

analog and audio signals. The DG441B, DG442B are

upgrades to the original DG441, DG442.

Combing low on-resistance (45 , typ.) with high speed

(tON 120 ns, typ.), the DG441B, DG442B are ideally

suited for Data Acquisition, Communication Systems,

Automatic Test Equipment, or Medical Instrumentation.

Charge injection has been minimized on the drain for use in

sample-and-hold circuits.

The DG441B, DG442B are built using Vishay Siliconix’s

high-voltage silicon-gate process. An epitaxial layer prevents

latchup.

When on, each switch conducts equally well in both

directions and blocks input voltages to the supply levels

when off.

FEATURES

• Low On-Resistance: 45 

• Low Power Consumption: 1 mW

• Fast Switching Action - tON: 120 ns
