Overview
The DG401DY-T1-E3 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates within a single supply voltage range of 13 V to 36 V or a dual supply range of ±7 V to ±22 V. The device features a maximum on-resistance of 45 Ohms and supports a continuous DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 150 ns and a maximum turn-off time of 100 ns. Power dissipation is rated at 600 mW, with a maximum supply current of 1 uA. It is housed in a 16-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual SPST configuration providing independent signal path control
- Low power consumption with minimal supply current draw
- High isolation performance characterized by low off-state leakage current
Applications
- Signal routing in data acquisition systems
- Multiplexing applications for sensor interfaces
- Programmable gain amplifier circuits
Procurement Notes
Verify the specific ordering suffix T1-E3 to confirm the tape-and-reel packaging format and RoHS compliance status. Ensure the component matches the exact Vishay Siliconix manufacturer designation to avoid confusion with similar variants in the DG40x series. Cross-reference the datasheet revision history for any recent parameter updates before finalizing procurement specifications.
Selection Notes
Select this component when dual isolated channels are required with moderate on-resistance constraints. The wide supply voltage capability allows compatibility with various logic levels and power rails. Verify that the 45 Ohm on-resistance meets the signal integrity requirements of the specific application circuit.
Part Context
This part belongs to the DG40x family of CMOS analog switches from Vishay Siliconix. The DG401 specifically denotes the dual SPST topology within this series. It shares common design characteristics with other members like the DG409 but differs in channel count and switching configuration.
Replacement Considerations
Publicly confirmed substitute part numbers include DG401DY and DG401DY-T1. These alternatives maintain the same functional specifications and pinout compatibility.
