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. up to "22 V, and have an improved continuous current rating of 30 m A. 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. These quad single-pole single-throw switches are designed for a wide variety of applications in telemunications, instrumentation, process control, puter peripherals, etc. An improved charge injection pensation design minimizes switching transients. The DG211B and DG212B can handle The DG211B is a normally closed switch and the DG212B is a normally open switch. (See Truth Table.)
