DG408DY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408DY-T1 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of eight inputs to a common output via a 3-bit binary address (A0, A1, A2). The device operates on single supplies from +5 V to +36 V or dual supplies from ±5 V to ±20 V. Key electrical parameters include a maximum on-resistance of 100 Ω, charge injection of 20 pC, and transition time of 160 ns. Supply current is typically 10 μA. It features TTL-compatible logic, break-before-make switching, and an enable function for stacking devices.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary crosstalk between adjacent channels.
• TTL-compatible control inputs allow direct interfacing with standard digital logic.
• Enable function allows resetting all switches to the off state for stacking multiple devices.
• Epitaxial layer design prevents latchup under operating conditions.

Analog Switches, Multiplexers, Demultiplexers Applications

• High-speed data acquisition systems
• Audio signal switching and routing
• Automated test equipment (ATE) systems
• Battery-powered instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. The -T1 suffix indicates tape and reel packaging, while the -E3 suffix denotes lead-free and RoHS compliance. Confirm that the component meets the required environmental specifications for the intended application before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel single-ended multiplexer is required with low power consumption and high voltage tolerance. Ensure the supply voltage range (+5 V to +36 V single or ±5 V to ±20 V dual) matches the system design. Verify that the 100 Ω on-resistance and 160 ns transition time meet the signal integrity requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG408 is part of the DG4xx series of high-performance CMOS analog multiplexers designed by Vishay Siliconix. This series utilizes a 44 V silicon-gate CMOS process to extend absolute maximum voltage ratings. The DG408 specifically provides single-ended switching, whereas the companion DG409 offers dual 4-channel differential switching capabilities within the same family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG408DY-E3 is a compatible alternative offering identical functionality in the SOIC-16 package with lead-free and RoHS-compliant terminations. Verify pinout compatibility and electrical specifications before substituting components in existing designs.
