DG419BDY

Overview

The DG419BDY is a precision monolithic quad SPDT CMOS analog switch manufactured by Vishay Siliconix. It operates within a ±15 V analog signal range and features an on-resistance of 25 Ω maximum at room temperature, extending to 34 Ω across the full operating range. The device supports dual supplies from ±5 V to ±20 V or single supplies up to 20 V. Key dynamic characteristics include a turn-on time of 89 ns maximum and a transition time of 87 ns maximum. It utilizes a narrow SOIC-8 surface-mount package with an operating temperature range of -40 °C to +85 °C.

Feature Summary

Break-before-make switching action guaranteed for reliable signal routing
CMOS logic compatible with TTL input levels for simple interfacing
Epitaxial layer construction prevents latchup under high voltage conditions

Applications

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

Procurement Notes

Verify the specific suffix 'DY' corresponds to the 8-pin Narrow SOIC package configuration required for the design. Confirm RoHS compliance status through official documentation as manufacturing locations may vary. Ensure the ordering part number matches the exact electrical specifications needed for the target application environment.

Selection Notes

Select this component when break-before-make timing is critical to prevent signal overlap in SPDT configurations. The low power consumption and small physical size make it suitable for portable applications. Verify that the supply voltage limits and leakage current requirements align with the system's analog signal range constraints.

Part Context

This part belongs to the DG417B/DG418B/DG419B family of precision analog switches. While DG417B and DG418B are SPST devices with opposite logic polarities, the DG419BDY specifically provides a single SPDT switch per channel. All variants share the same high-voltage silicon gate process technology for superior performance.
