DG419BDY-T1

Overview

The DG419BDY-T1 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a temperature range of -40 °C to +85 °C and utilizes an 8-pin Narrow SOIC package. The device supports dual supply voltages up to ±20 V or single supplies up to 36 V, with an analog signal range of ±15 V under dual supply conditions. Key electrical parameters include a maximum on-resistance of 25 Ω at room temperature and 29 Ω across the full temperature range. Turn-on time is specified at a maximum of 89 ns, while turn-off time reaches 80 ns. Supply current remains low at 1 µA maximum.

Feature Summary

Break-before-make switching action ensures reliable signal routing without shorting paths.
CMOS logic compatibility allows direct interfacing with standard TTL and CMOS control circuits.
Epitaxial layer construction prevents latchup for improved operational reliability.

Applications

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

Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status as the base part number may have non-compliant variants. Ensure the ordering code matches the required temperature grade and package style for integration into the design.

Selection Notes

Select this component for applications requiring high-speed switching with minimal signal distortion. The 25 Ω on-resistance suits general-purpose analog signal routing. Verify that the 89 ns transition times meet system timing requirements compared to faster alternatives in the series.

Part Context

This part belongs to the DG417B/DG418B/DG419B family of precision analog switches. While the DG417B and DG418B are configured as Single Pole Single Throw (SPST) switches, the DG419B variant provides a Single Pole Double Throw (SPDT) configuration. All share the same high-voltage silicon gate process technology.
