DG309DY+T

Overview

The DG309DY+T is a quad single-pole single-throw normally-closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates four independent SPST-NC switches within a 16-SOIC surface-mount package. The device operates on a single supply voltage ranging from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 ohms, a charge injection of -10pC, and an off-state leakage current of 5nA. Switching times are specified at 250ns for turn-on and 150ns for turn-off. The component supports an operating temperature range of -40°C to 85°C.

Feature Summary

Integrates four independent SPST-NC analog switches in a compact 16-pin SOIC package
Operates with TTL/CMOS logic compatible control inputs
Provides low off-state leakage current for signal isolation applications

Applications

Signal routing in data acquisition systems
Audio switching circuits
Instrumentation input multiplexing

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS3 compliance status as indicated in official documentation. Check manufacturer announcements for obsolescence notices, as this part may be discontinued. Ensure the supplier provides valid traceability documents matching the Analog Devices or Maxim Integrated origin.

Selection Notes

Select this component when a normally-closed configuration is required for the analog signal path. Compare on-resistance values against system tolerance requirements, noting the 100-ohm maximum. Verify that the 5V minimum single-supply operation aligns with available power rails. Consider the -10pC charge injection impact on precision applications compared to lower-injection alternatives.

Part Context

This part belongs to the DG309 series of CMOS analog switches. It shares functional similarities with other devices in the family but differs in contact state (normally closed vs. normally open). The DG309 complements parts like the DG308, which offers normally-open contacts. Both utilize similar pinouts and control logic for interchangeability in design architectures requiring different default states.
