| DG201B/202B Vishay Siliconix Improved Quad CMOS Analog Switches 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.)
