Overview
The DG442LDY-T1-E3 is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features a maximum on-resistance of 17 Ω and fast switching times with a turn-on time of 20 ns and turn-off time of 12 ns. It offers low leakage current of 0.25 nA, 2000 V ESD protection, and TTL/CMOS compatibility. The component is housed in a 16-pin narrow SOIC package and supports an operating temperature range from -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 interface 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 RoHS compliance status as indicated by the E3 suffix. Ensure the narrow SOIC package dimensions match the design requirements. Check for halogen-free certification if required by environmental standards. Validate the operating temperature range against system constraints.
Selection Notes
Select the DG442LDY-T1-E3 for applications requiring low-voltage analog signal switching with high speed. Consider the complementary nature of the DG441L series if opposite control logic is needed. Evaluate the on-resistance flatness over the signal range for distortion-sensitive circuits. Verify that the power dissipation limits are not exceeded in the intended thermal environment.
Part Context
This part belongs to the DG441L/DG442L family of precision monolithic quad SPST low-voltage CMOS analog switches. These devices are designed as companion parts with improved performance compared to earlier industry standard versions. They utilize BiCMOS wafer fabrication technology to achieve low power consumption and high-speed switching capabilities suitable for various signal processing applications.
Replacement Considerations
DG441LDY-T1-E3 is a pin-compatible alternative within the same datasheet offering opposite logic control. Other variants in the DG442L family include DG442LDQ-T1-E3 for TSSOP packaging.
