DG201BDY

The Vishay Siliconix DG201BDY is an improved quad single-pole single-throw (SPST) analog switch fabricated using a proprietary silicon gate CMOS process. This results in enhanced performance characteristics such as lower on-resistance, reduced leakage, and faster switching speeds compared to previous generations.

Key electrical specifications include a supply voltage rating of ±22 V, a typical on-resistance of 45 Ω, and a typical leakage current of 20 pA. The device features fast switching times with a tON of 120 ns and low glitching with a charge injection of 1 pC. It also has an improved continuous current rating of 30 mA.

Designed for a wide range of applications including industrial instrumentation, test equipment, communications systems, and computer peripherals, the DG201BDY offers a simple logic interface and single-supply operation capability. It is available in a 16-SOIC package, suitable for surface mount applications.

The DG201B series is superior to the DG201A and DG202, offering benefits like a wide analog signal range, higher accuracy, and reduced power consumption. An epitaxial layer prevents latchup, and the switches provide true bi-directional performance in the on condition while blocking signals to the supply voltages in the off condition.
