Overview
The Vishay Siliconix DG441BDJ is a monolithic quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It provides high-speed switching with a typical turn-on time of 120 ns and low on-resistance of 45 Ω at room temperature, extending to a maximum of 95 Ω across the full operating range. The device supports dual supplies from ±7 V to ±22 V or a single supply up to 36 V, with an analog signal range matching the supply rails. Power consumption is minimized at 1 mW, and charge injection is limited to -1 pC, making it suitable for precision applications.
Feature Summary
- Monolithic quad SPST configuration with TTL/CMOS-compatible logic inputs
- High-voltage silicon-gate process with epitaxial layer preventing latchup
- Low power consumption of 1 mW with fast switching action
- Minimized charge injection (-1 pC) optimized for sample-and-hold circuits
Applications
- Data Acquisition Systems
- Communication Systems
- Automatic Test Equipment
- Medical Instrumentation
- Audio Switching
Procurement Notes
Verify the specific ordering suffix against current Vishay documentation to confirm package type and compliance status. The base part number corresponds to the 16-pin Plastic DIP variant. Confirm RoHS compliance requirements by checking for the -E3 suffix if lead-free material is mandatory for the assembly process.
Selection Notes
Select the DG441BDJ when a through-hole 16-pin DIP package is required for prototyping or legacy board designs. Ensure the application voltage does not exceed the absolute maximum ratings of 44 V between supplies. Verify that the 80 Ω to 95 Ω maximum on-resistance meets the signal integrity requirements compared to lower-resistance alternatives.
Part Context
The DG441BDJ belongs to the DG441B/DG442B series, which are upgraded versions of the original DG441/DG442 devices. This family utilizes Vishay's high-voltage silicon-gate process to deliver improved performance characteristics such as reduced charge injection and faster switching speeds while maintaining compatibility with standard digital logic levels.
Replacement Considerations
DG441BDJ-E3 is the RoHS-compliant version of this component. For surface-mount requirements, the DG441BDY-E3 (SOIC-16) offers equivalent electrical specifications in a different package form factor.
