1 / 10 page Vishay Siliconix DG201B/202B Document Number: 70037 S-71155–Rev. H, 11-Jun-07 www.vishay.com 1 Improved Quad CMOS Analog Switches FEATURES • ± 22 V Supply Voltage Rating • TTL and CMOS Compatible Logic • Low On-Resistance - rDS(on): 45 Ω • Low Leakage - ID(on): 20 pA • Single Supply Operation Possible • Extended Temperature Range • Fast Switching - tON: 120 ns • Low Glitching - Q: 1 pC BENEFITS • Wide Analog Signal Range • Simple Logic Interface • Higher Accuracy • Minimum Transients • Reduced Power Consumption • Superior to DG201A/202 • Space Savings (TSSOP) APPLICATIONS • Industrial Instrumentation • Test Equipment • Communications Systems • Disk Drives • Computer Peripherals • Portable Instruments • Sample-and-Hold Circuits DESCRIPTION The DG201B/202B analog switches are highly improved versions of the industry-standard DG201A/202. These devices are fabricated in Vishay Siliconix’ proprietary silicon gate CMOS process, resulting in lower on-resistance, lower leakage, higher speed, and lower power consumption. These quad single-pole single-throw switches are designed for a wide variety of applications in telecommunications, instrumentation, process control, computer peripherals, etc. An improved charge injection compensation design minimizes switching transients. The DG201B and DG202B can handle up to ± 22 V input signals, and have an improved continuous current rating of 30 mA. An epitaxial layer prevents latchup. All devices feature true bi-directional performance in the on condition, and will block signals to the supply voltages in the off condition. The DG201B is a normally closed switch and the DG202B is a normally open switch. (See Truth Table.)
