DG212BDJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG212BDJ-E3 is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches with normally open logic, where a logic high turns the switch on. The device supports dual supply voltages from ±4.5 V to ±22 V or a single supply from +4.5 V to +25 V. Key electrical parameters include a maximum drain-source on-resistance of 85 Ω at room temperature and 100 Ω across the full temperature range (-40 °C to +85 °C). Continuous current handling is rated at 30 mA, with peak pulsed currents up to 100 mA. Switching times are specified as 300 ns for turn-on and 200 ns for turn-off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Normally open SPST configuration compatible with TTL and CMOS logic levels
• Low charge injection design minimizes switching transients
• Epitaxial layer prevents latch-up under high voltage conditions
• Bi-directional signal performance in the on condition

Analog Switches, Multiplexers, Demultiplexers Applications

• Industrial instrumentation
• Test equipment
• Sample-and-hold circuits
• Computer peripherals

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix -E3 confirms RoHS compliance and lead-free terminations. Confirm the package type matches the required PCB footprint, specifically the 16-pin plastic DIP format. Ensure the operating environment stays within the specified -40 °C to +85 °C temperature range to maintain guaranteed electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open analog switch is required for signals up to ±22 V. Compare against the DG211B variant if a normally closed configuration is needed instead. Consider the DG411 series for applications requiring lower on-resistance or faster switching speeds. Verify power dissipation limits relative to ambient temperature derating requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG211B/DG212B family of improved quad CMOS analog switches. It serves as an enhanced successor to the industry-standard DG211/212 devices, offering lower on-resistance, reduced leakage, and higher speed. The DG212B specifically provides the normally open logic state, distinguishing it from the DG211B's normally closed operation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411 series is documented as a drop-in replacement offering lower on-resistance and faster switching. The DG211B is functionally similar but utilizes normally closed logic rather than normally open.
