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 DG211B and DG212B can handle up to 22 V, 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 levels in the off condition. The DG211B is a normally closed switch and the DG212B is a normally open switch. (See Truth Table.) Logic DG211B DG212B ON OFF OFF ON Logic “0” 0.8 V Logic “1” 2.4 V
