DG212BDY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG212BDY-T1-E3 is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches in a 16-pin Narrow SOIC package, designed for TTL and CMOS logic compatibility. The device supports dual supply voltages up to ±22 V or single supply operation up to +25 V. Key electrical parameters include a maximum on-resistance of 85 Ω, a turn-on time of 300 ns, and a turn-off time of 200 ns. It operates within an extended temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and reel specifications. Ensure the component meets RoHS compliance requirements if applicable to the assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open SPST configuration is required for signal routing. The device is suitable for applications needing bi-directional signal handling with low leakage current. Consider the 85 Ω on-resistance and 30 mA continuous current rating to ensure compatibility with the target analog signal levels and load requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG211B/DG212B series, which are improved versions of industry-standard analog switches. The DG212B variant specifically provides a normally open switch, contrasting with the DG211B's normally closed configuration. Both share identical electrical characteristics and pinouts, differing only in the polarity of the selection logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411 series serves as a drop-in replacement offering lower on-resistance and faster switching speeds. Designers should verify that the logic interface remains compatible, as the DG411 series maintains TTL and CMOS compatibility while providing enhanced performance metrics over the original DG212B design.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the DG211B and DG212B?

The primary difference is the switch state: the DG211B is a normally closed switch (Logic '0' turns it ON), while the DG212B is a normally open switch (Logic '1' turns it ON).

Can the DG212BDY-T1-E3 operate with a single supply voltage?

Yes, the device supports single supply operation ranging from +4.5 V to +25 V, in addition to dual supply operation up to ±22 V.

What is the maximum analog signal range for this switch?

With a ±15 V supply, the analog signal range is typically -15 V to +15 V. With a single +12 V supply, the range is 0 V to 12 V.
