DG201BDY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BDY-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It operates with dual supplies ranging from ±4.5 V to ±22 V or a single supply from +4.5 V to +25 V. The device features a maximum on-resistance of 85 Ω at room temperature and up to 200 Ω across the full operating range. Switching times are specified with a maximum turn-on time of 300 ns and a maximum turn-off time of 200 ns. Continuous current handling is rated at 30 mA, with an off-leakage current of 5 nA at room temperature.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Quad SPST configuration with TTL and CMOS compatible logic inputs
• Extended signal range capability supporting input signals up to ±22 V
• Improved charge injection compensation design minimizes switching transients
• Epitaxial layer construction prevents latchup under stress conditions

• Portable instruments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' confirms lead-free and RoHS compliance status as defined in the ordering information table. Confirm the 'DY' designation corresponds to the 16-pin narrow SOIC package type required for the target PCB layout. Ensure the operating temperature range matches the 'D' suffix specification of -40 °C to +85 °C for the application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed quad analog switch is required. The DG201B differs from the DG202B by its default state; the DG201B is ON when the logic input is low. Verify that the 85 Ω on-resistance meets the signal integrity requirements compared to lower resistance alternatives. Ensure the 30 mA continuous current rating is sufficient for the load connected to the switch channels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG201B/DG202B family, which represents improved versions of the industry-standard DG201A and DG202 switches. Manufactured using a proprietary silicon gate CMOS process, the B-series offers lower on-resistance, reduced leakage, faster switching speeds, and lower power consumption compared to previous generations.
