DG442BDY-E3

Overview

The DG442BDY-E3 is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates with dual supplies ranging from ±15 V to ±20 V or a single supply up to 16 V. The device features a typical on-resistance of 45 Ω and a maximum of 80 Ω at room temperature, with a turn-on time of 120 ns and turn-off time of 65 ns. Power consumption is low at 1 mW, and it supports an analog signal range of ±15 V under dual supply conditions.

Feature Summary

• High-speed switching action for analog and audio signals
• Low charge injection suitable for sample-and-hold circuits
• TTL/CMOS-compatible logic control
• Epitaxial layer prevents latchup

Applications

• Data Acquisition Systems
• Communication Systems
• Automatic Test Equipment
• Medical Instrumentation
• Audio Switching

Procurement Notes

Verify the component against the official Vishay datasheet document number 72625 to confirm specifications. Ensure the package matches the 16-pin Narrow SOIC format. Check RoHS compliance documentation as indicated in the ordering information section. Validate that the part number suffix corresponds to the correct lead-free status.

Selection Notes

Select this component when low on-resistance and fast switching are required for analog signal routing. It serves as an upgrade to the original DG442 model. Consider the power dissipation limits of the SOIC-16 package during thermal design. Verify compatibility with the system's logic voltage levels for proper channel control.

Part Context

This part belongs to the DG441B/DG442B series of improved quad SPST CMOS analog switches. It is designed to provide high-speed, low-error switching capabilities. The device utilizes a high-voltage silicon-gate process for robust performance in various electronic applications.
