DG303BDY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303BDY-E3 is a monolithic CMOS analog switch from the Vishay Siliconix DG303B family, housed in a 14-SOIC surface-mount package. It features two independent SPDT (Single Pole Double Throw) channels with break-before-make switching action. The device supports dual supply voltages ranging from ±7 V to ±22 V or single supplies up to 36 V. Key electrical parameters include a maximum on-resistance of 50 Ω at room temperature and 75 Ω across the full operating range (-40 °C to +85 °C). Turn-on time is typically 150 ns, while turn-off time is 130 ns. The component exhibits low off-leakage current (±5 nA typical) and charge injection of 8 pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify RoHS compliance status through official manufacturer documentation, as historical production data indicates variations between leaded and lead-free versions. Confirm that the SOIC-14 package dimensions match your PCB footprint requirements. Ensure voltage ratings align with your specific circuit design before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required in a compact surface-mount format. Consider the 50 Ω on-resistance limit for signal integrity requirements. Verify that the input logic levels meet the specified thresholds for reliable operation within your system's voltage environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG300B/DG301B/DG302B/DG303B series of CMOS analog switches. The DG303B variant specifically provides two SPDT channels, distinguishing it from the SPST configurations of the DG300B and DG302B, and the dual SPDT arrangement of the DG301B.
