DG419BDQ-T1-E3

Overview

The DG419BDQ-T1-E3 is a precision monolithic quad SPDT CMOS analog switch manufactured by Vishay Siliconix. It operates within a temperature range of -40 °C to +85 °C and utilizes an MSOP-8 surface-mount package. The device supports dual supply voltages up to ±15 V or single supplies up to 20 V, with an analog signal range of ±15 V. Key electrical parameters include a maximum on-resistance (RDS(on)) of 25 Ω at room temperature and 29 Ω across the full temperature range. Dynamic characteristics feature a maximum turn-on time of 89 ns and a turn-off time of 80 ns under standard test conditions.

Feature Summary

Break-before-make switching action ensures reliable signal routing without shorting outputs.
High-voltage silicon gate process provides superior switching performance and latchup protection.
TTL and CMOS compatible logic levels simplify interfacing with digital control systems.

Applications

Precision test equipment
Battery powered systems
Sample-and-hold circuits

Procurement Notes

Verify the specific suffix 'D' for the -40 °C to +85 °C operating temperature range and 'Q' for the MSOP-8 package configuration. Confirm RoHS compliance status via the manufacturer's documentation as ordering suffixes may impact environmental certifications. Ensure the datasheet revision matches current design requirements before finalizing procurement orders.

Selection Notes

Select this component when a single SPDT channel is required in a compact MSOP-8 footprint. The 25 Ω on-resistance suits applications requiring moderate signal integrity. Verify that the 89 ns switching speed meets system timing constraints. Consider the DG419BDY variant if a SOIC-8 package is preferred for the same electrical specifications.

Part Context

This part belongs to the DG417B/DG418B/DG419B family of precision analog switches. While the DG417B and DG418B are configured as SPST switches, the DG419B provides a single SPDT configuration. The BDQ suffix specifically denotes the MSOP-8 package option within this series, distinguishing it from the SOIC-8 (BDY) or MiniDIP (BDJ) variants.
