DG9431EDY-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9431EDY-T1-GE3 is a monolithic CMOS single-pole double-throw (SPDT) analog switch designed for precision signal switching applications. Operating on a single supply voltage ranging from +2.7 V to +5.5 V, it features a typical drain-source on-resistance of 17 Ω at 5 V and low charge injection of approximately 0.78 pC. The device guarantees a maximum switch-on leakage current of 100 pA at room temperature and offers fast switching times with turn-on and turn-off delays of 32 ns and 10 ns, respectively. It provides high ESD tolerance exceeding 8 kV (HBM) and 1 kV (CDM), making it suitable for low-voltage instrumentation and healthcare devices.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'T1' confirms tape and reel packaging containing 2500 units per reel. Confirm the 'E3' suffix indicates RoHS compliance and halogen-free status. Ensure the 'D' suffix matches the required -40 °C to +85 °C operating temperature range. Validate that the SOIC-8 package variant aligns with PCB footprint requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT configuration with low on-resistance is required for signals up to the supply rail. The DG9431EDY-T1-GE3 is appropriate for designs needing minimal charge injection to preserve signal integrity in sample-and-hold or ADC front-end applications. Consider the 8-pin SOIC package for standard surface-mount assembly processes requiring narrow body footprints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Vishay Siliconix DG9431E family of precision analog switches. The specific model DG9431EDY-T1-GE3 denotes the 8-lead narrow SOIC package variant supplied in tape and reel format. It shares functional characteristics with the DG9431EDV-T1-GE3, which utilizes a 6-lead TSOP package, offering design flexibility based on available board space and pin count constraints.
