DG309BDQ-T1-E3

Overview

The DG309BDQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch in a 16-pin TSSOP package. It operates with dual supplies of ±4 V to ±22 V or a single supply of 8 V to 44 V. The device features a maximum on-resistance of 100 Ω and a maximum turn-on time of 200 ns. Supply current is limited to 5 µA, while off-leakage currents are typically 0.5 nA at room temperature. It supports bi-directional signal handling and includes an epitaxial layer for latchup prevention.

Feature Summary

CMOS fabrication process enabling low power consumption and high accuracy
Improved charge injection compensation design minimizes switching transients
Epitaxial layer integration prevents latchup under stress conditions
True bi-directional performance allows blocking signals up to supply levels

Applications

Sample-and-hold circuits
Industrial instrumentation
Test equipment
Communications systems

Procurement Notes

Verify the RoHS-compliant suffix '-E3' matches the specific procurement requirement. Confirm the 'T1' suffix indicates tape and reel packaging suitable for automated assembly. Ensure the component source is traced directly to Vishay Siliconix authorized channels to guarantee authenticity and lot traceability.

Selection Notes

Select this part when a normally closed SPST configuration is required within a quad switch array. Verify that the 100 Ω maximum on-resistance meets the signal integrity requirements. Ensure the operating voltage range aligns with the ±22 V absolute maximum rating and check thermal dissipation limits for the TSSOP package.

Part Context

This component belongs to the DG308B/DG309B series, representing improved versions of the industry-standard DG308A/DG309. The DG309 variant specifically provides a normally closed switch state, contrasting with the normally open DG308B. Both share identical electrical characteristics and pinouts.
