DG418BDY-T1

Overview

The DG418BDY-T1 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a ±15 V dual supply range and supports single-supply operation up to +12 V. The device features a maximum on-resistance of 25 Ω at room temperature, with a turn-on time of 89 ns and a turn-off time of 80 ns under standard test conditions. It utilizes an SOIC-8 surface-mount package and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• High-voltage silicon gate process ensures superior switching performance and latchup prevention.
• TTL and CMOS compatible logic control for simple interfacing.
• Low power consumption and low leakage currents suitable for battery-powered systems.

Applications

• Precision test equipment
• Precision instrumentation
• Sample-and-hold circuits

Procurement Notes

Verify the component status as obsolete or end-of-life through official manufacturer channels before design finalization. Confirm RoHS compliance details and check for available replacement part numbers such as the DG418BDY-T1-E3 variant. Ensure all technical specifications align with current project requirements prior to procurement.

Selection Notes

Select this component when a quad SPST configuration with low on-resistance is required in an SOIC-8 package. Verify that the ±15 V signal range meets system needs. Consider the DG417B for inverted logic control or the DG419B if break-before-make switching is necessary for the specific application circuit.

Part Context

This part belongs to the DG417B/DG418B/DG419B series of precision monolithic quad SPST CMOS analog switches. The DG418B specifically responds to opposite control logic levels compared to the DG417B. The 'DY' suffix indicates the narrow SOIC-8 package, while the '-T1' suffix denotes tape and reel packaging for automated assembly.

Replacement Considerations

Public documentation identifies the DG418BDY-T1-E3 as a compliant alternative version of this component.
