DG441BDY

Overview

The DG441BDY is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±7 V to ±22 V for dual supplies, or 13 V to 36 V for single supplies. The device features a typical on-resistance of 45 Ω and a maximum of 80 Ω at room temperature. Switching times are specified with a typical turn-on time of 120 ns and turn-off time of 65 ns. Power consumption is low at approximately 1 mW, and the package is a 16-pin narrow SOIC.

Feature Summary

Monolithic quad SPST configuration designed for high-speed switching of analog and audio signals
Low charge injection capability optimized for use in sample-and-hold circuits
TTL and CMOS compatible logic levels for simple interfacing
Epitaxial layer construction prevents latchup under high-voltage conditions

Applications

Data acquisition systems
Communication systems
Automatic test equipment
Medical instrumentation
Sample-and-hold circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and compliance status. Ensure that the component meets all required environmental standards and material categorization definitions before finalizing procurement specifications.

Selection Notes

Select this component when low on-resistance and fast switching speeds are critical for signal integrity. Consider the power dissipation limits and thermal derating requirements based on the operating ambient temperature and board layout constraints.

Part Context

The DG441B series serves as an improved upgrade to the original DG441 devices. It utilizes a high-voltage silicon-gate process to deliver enhanced performance characteristics while maintaining compatibility with standard logic families used in industrial and scientific applications.
