DG9431DY-T1-E3

Overview

The DG9431DY-T1-E3 is a low-voltage single-pole/double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a +2.7 V to +5 V supply range and features a maximum on-resistance of 20 Ω at 5 V. The device provides fast switching with turn-on and turn-off times of 35 ns and 20 ns, respectively. It exhibits low leakage current, with a maximum channel-on leakage of 200 pA, and minimal charge injection of 1 pC. The component is housed in an SOIC-8 surface-mount package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

Low voltage operation optimized for portable battery-powered systems
High-speed switching with guaranteed break-before-make timing
TTL and CMOS logic compatible interface
Integrated ESD protection exceeding 2000 V

Applications

Battery operated systems
Portable test equipment
Sample and hold circuits
Cellular phones
Communication systems

Procurement Notes

Verify the specific suffix against the manufacturer's documentation to confirm lead-free status and RoHS compliance. Ensure the ordering code matches the required package type, as the DG9431 series includes both TSOP-6 and SOIC-8 variants. Confirm availability through authorized distributors, as manufacturing locations may vary while maintaining reliability standards.

Selection Notes

Select this component for applications requiring low power consumption and high accuracy in signal routing. The SOIC-8 package offers a balance between board space efficiency and thermal performance compared to smaller packages. Verify that the input logic levels align with the system's control signals, as the device requires specific voltage thresholds for reliable switching.

Part Context

The DG9431 belongs to Vishay Siliconix's low-voltage analog switch family, designed using a BCD-15 process. This technology ensures latchup prevention and robust performance in compact designs. The product line emphasizes efficient use of board space, making it suitable for dense circuit layouts in consumer electronics and communication devices.
