Overview
The DG442LDY-T1 is a precision monolithic quad SPST low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features an on-resistance of 17 Ω, turn-on time of 20 ns, and turn-off time of 12 ns. It supports TTL and CMOS logic inputs with low leakage current of 0.25 nA and 2000 V ESD protection. Packaged in a 16-pin narrow SOIC (SOIC-16), it functions within a temperature range of -40 °C to +85 °C.
Feature Summary
- Low voltage operation compatible with single and dual power supplies
- Fast switching speeds with minimal insertion loss
- TTL and CMOS logic input compatibility
- High off-isolation and channel-to-channel crosstalk performance
Applications
- Precision automatic test equipment
- Precision data acquisition systems
- Communication systems including SDSL and DSLAM
- Audio and video signal routing
- Battery powered systems
Procurement Notes
Verify the specific suffix T1 indicates tape and reel packaging when sourcing this component. Confirm the LDY designation corresponds to the narrow SOIC package variant. Ensure the manufacturer is identified as Vishay Siliconix for accurate part tracing. Check RoHS compliance status if required for your assembly process.
Selection Notes
Select the DG442LDY-T1 when opposite control logic is required compared to the DG441L series. Choose this part for applications needing fast switching under low voltage conditions. Verify that the 17 Ω on-resistance meets the signal integrity requirements of the target circuit design.
Part Context
This component belongs to the DG441L/DG442L family of precision analog switches. These devices are designed as pin-for-pin compatible companion units using BiCMOS wafer fabrication technology. They offer improved performance over standard industry counterparts while maintaining simple interfacing capabilities.
Replacement Considerations
DG441LDY-T1-E3 serves as the complementary logic variant within the same package family.
