Overview
The DG3157DL-T1-GE3 is a single-channel SPDT analog switch IC manufactured by Vishay Siliconix. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 15 Ohms. The device supports a continuous DC switch current of 50 mA with a maximum power dissipation of 250 mW. Electrical performance includes a maximum propagation delay of 4 ns, turn-on time of 2.6 ns, and turn-off time of 2.6 ns. It functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Single-pole double-throw (SPDT) configuration for signal routing
- Low on-resistance for minimal signal attenuation
- Fast switching speeds suitable for high-frequency applications
- Wide single-supply voltage operation
Applications
- Portable instrumentation signal conditioning
- Battery-powered measurement systems
- Data acquisition channel selection
Procurement Notes
Verify the specific suffix 'DL' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives as indicated in the component datasheet. Confirm availability status directly with authorized distributors, as this part number may be subject to discontinuation or limited stock conditions.
Selection Notes
Select this component when a single SPDT switch is required in a compact SC-70-6 package. It is appropriate for designs needing low on-resistance and fast switching under single-supply voltages between 1.65 V and 5.5 V. Consider thermal constraints due to the 250 mW power dissipation limit in small packages.
Part Context
This component belongs to the DG series of analog switches from Vishay Siliconix. It serves as a successor or alternative to legacy parts like the DG3157DL-T1. The device integrates CMOS technology to provide high-speed switching capabilities in a miniature surface-mount footprint, targeting space-constrained electronic designs.
Replacement Considerations
The DG3157EDL-T1-GE3 is listed as a recommended alternative. Verify pin compatibility and electrical parameter differences, such as the higher on-resistance (11 Ohms vs 15 Ohms) and slower switching times (32 ns vs 2.6 ns), before substitution.
