DG306BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG306BDJ is a monolithic CMOS analog switch from the Vishay Siliconix DG304B/306B/307B series, housed in a 14-pin Plastic DIP package. It contains four independent Single-Pole Single-Throw (SPST) switches. The device supports dual supply voltages ranging from ±5 V to ±20 V or single supply operation up to +20 V with the negative rail grounded. Key electrical parameters include a maximum on-resistance of 75 Ω and a turn-on time of 110 ns. It operates within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status by checking for the -E3 suffix designation, as standard versions may contain lead. Validate datasheet revision D specifications against current manufacturing capabilities before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring four isolated analog paths controlled by CMOS logic levels. Ensure the application voltage does not exceed the absolute maximum ratings of ±20 V. Verify that the required switching speed meets the 110 ns turn-on specification and that the package footprint accommodates the 14-pin DIP form factor.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG304B/DG306B/DG307B family of CMOS analog switches. The DG306B variant specifically provides four SPST channels, distinguishing it from the DG304B which offers two SPDT channels and the DG307B which features two SPDT channels with break-before-make timing.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic threshold voltage for turning the switch on?

A logic high input voltage of 11 V or greater turns the switch on.

Does the DG306BDJ support single supply operation?

Yes, single supply operation is allowed by connecting the V- rail to 0 V.

What is the maximum analog signal range?

The analog signal range extends from the negative supply voltage to the positive supply voltage.
