DG201BDJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BDJ-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix in a 16-pin plastic DIP 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. The component supports continuous current ratings of 30 mA and functions within an extended temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' confirms lead-free compliance and RoHS Directive 2002/95/EC adherence. Confirm the 'DJ' designation corresponds to the 16-pin Plastic DIP package. Ensure the order quantity matches the manufacturer's standard tube packaging requirements. Validate that the application environment remains within the specified -40 °C to +85 °C operational limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed SPST configuration is required, as the DG201B defaults to ON with Logic 0. Compare against the DG202B if a normally open configuration is needed instead. Consider the 85 Ω on-resistance limit for signal integrity requirements. Verify power dissipation derating factors if operating above 75 °C ambient temperature.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201B/DG202B family, which serves as an improved version of the industry-standard DG201A and DG202 devices. The B-series offers lower on-resistance, reduced leakage, faster switching speeds, and lower power consumption compared to previous generations while maintaining compatibility with standard interfaces.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the DG201B switches?

The DG201B is a normally closed switch, meaning the channels are ON when the logic input is Low (0).

How does the DG201B handle signals exceeding supply voltages?

Signals on source, drain, or input pins exceeding V+ or V- will be clamped by internal diodes.

What is the maximum power dissipation for the 16-pin plastic DIP package?

The maximum power dissipation is 470 mW, with a derating factor of 6.5 mW/°C above 75 °C.
