DG442BDN-T1-E4

Overview

The DG442BDN-T1-E4 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix in a 16-pin QFN (4x4 mm) surface-mount package. It operates with dual supplies ranging from ±7 V to ±22 V or a single supply of 13 V to 36 V. The device features a maximum on-resistance of 80 Ω, a typical turn-on time of 120 ns, and a maximum of 220 ns. Power consumption is low at 1 µA, with a power dissipation rating of 850 mW for the QFN package. It supports an analog signal range up to the supply rails and includes TTL/CMOS-compatible logic inputs.

Feature Summary

High-speed switching action optimized for data acquisition and communication systems
Minimized charge injection suitable for sample-and-hold circuit applications
TTL and CMOS compatible logic control for simple interfacing

Applications

Data Acquisition Systems
Communication Systems
Sample-and-Hold Circuits
Automatic Test Equipment
Medical Instrumentation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot traceability requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering. Validate that the ordering suffix matches the required tape and reel packaging specifications for automated assembly processes.

Selection Notes

Select this component when high-speed switching and low error rates are required for analog signals. The DG442B variant provides normally-off logic configuration, contrasting with the DG441B's normally-on behavior. Consider the 16-QFN package for compact board layouts requiring surface-mount technology. Verify that the operating voltage range aligns with the system's single or dual supply capabilities.

Part Context

This part belongs to the DG441B/DG442B series, which are upgraded versions of the original DG441 and DG442 analog switches. The series utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latchup. The DG442B specifically offers a normally-off configuration, whereas the DG441B is normally-on, both sharing similar electrical characteristics and pinouts.
