DG2731DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2731DN-T1-E4 is a low voltage, dual single-pole/double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply ranging from 1.65 V to 4.3 V and features a maximum on-resistance of 0.4 Ω at 3.6 V. The device provides fast switching with a turn-on time of up to 110 ns and a turn-off time of up to 30 ns. It includes greater than 300 mA latch-up protection per JESD78 and guarantees break-before-make timing. The component utilizes a DFN-10 package with nickel-palladium-gold terminations.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix E4 indicates lead-free nickel-palladium-gold terminations compliant with JEDEC standards. Confirm the DFN-10 package dimensions match the design footprint requirements. Ensure the operating temperature range covers the intended environmental conditions. Check for RoHS compliance documentation if required by local regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high-speed switching are required within a single-supply voltage range. The DG2731 variant is appropriate for designs needing two separate control inputs rather than an enable pin. Consider the DFN-10 package size constraints and thermal dissipation capabilities during layout planning.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2731/2732/2733 family of low voltage analog switches. While functionally similar regarding electrical performance, the DG2731 differs from the DG2732 and DG2733 by utilizing two separate control pins instead of a shared enable pin. All variants share the same core CMOS process technology and package options.
