DG212BDQ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG212BDQ-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 TSSOP package, designed for TTL and CMOS logic compatibility. The device supports dual supply operation from ±4.5 V to ±22 V or single supply from +4.5 V 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. Leakage currents are specified at a maximum of 5 nA across the full temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against the official Vishay datasheet Document Number 70040 to confirm the specific TSSOP-16 package configuration and RoHS compliance status. Ensure that the ordering suffix matches the required lead-free specifications and packaging format before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open SPST configuration is required within a quad switch array. The DG212 variant differs from the DG211 by its logic polarity, where a high input turns the switch on. Verify that the 85 Ω on-resistance meets the application's signal integrity 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 B-series devices offer lower on-resistance, reduced leakage, and faster switching speeds compared to previous generations while maintaining pin compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411 series serves as a drop-in replacement offering lower on-resistance and faster switching times. Designers should verify logic polarity differences between the DG212 and alternative parts to ensure correct circuit functionality.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between DG212 and DG211?

The DG212 is a normally open switch where a logic high turns it on, whereas the DG211 is a normally closed switch where a logic low turns it on.

Does the DG212BDQ-E3 support single supply operation?

Yes, the device supports single supply operation ranging from +4.5 V to +25 V.

What is the maximum power dissipation for the TSSOP package?

The maximum power dissipation for the 16-Pin Narrow SOIC and TSSOP packages is 640 mW.
