DG442BDY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442BDY-T1-E3 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features a typical on-resistance of 45 Ω and fast switching times with a maximum turn-on time of 220 ns and turn-off time of 120 ns under dual supply conditions. The device operates with single supplies from 12 V to 36 V or dual supplies ranging from ±7 V to ±22 V. It utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latchup, ensuring low power consumption of 1 mW and minimal charge injection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives as indicated in the official datasheet. Confirm that the component meets the required operating temperature range of -40 °C to +85 °C for the intended application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high-speed switching are critical requirements. The DG442B variant provides normally closed functionality compared to the DG441B. Consider the single-supply capability if power supply constraints exist. Verify that the logic input voltage levels align with the system's control signals to ensure proper switching thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG442BDY-T1-E3 belongs to the DG441B/DG442B family, which are upgraded versions of the original DG441 and DG442 switches. These devices are designed for high-speed, low-error switching of analog and audio signals. The 'BDY' designation indicates a 16-pin Narrow SOIC package, while the '-T1' suffix typically denotes tape and reel packaging for automated assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG441BDY-T1-E3 is a functional alternative within the same family, differing primarily in switch state configuration (normally open vs. normally closed). Verify pin compatibility and logic truth table differences before substitution.
