DG408DQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408DQ-T1-E3 is an 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of eight inputs to a common output based on a 3-bit binary address (A0, A1, A2). The device operates with a single supply voltage ranging from 5 V to 36 V or dual supplies from ±5 V to ±20 V. Key electrical specifications include a maximum drain-source on-resistance of 100 Ω, a transition time of 160 ns, and a typical off-isolation of -75 dB at 1 MHz. It features TTL-compatible logic inputs and break-before-make switching to prevent crosstalk. The component is housed in a 16-lead TSSOP package and supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary crosstalk between adjacent channels during transitions.
• TTL-compatible control inputs allow direct interfacing with standard digital logic across the full operating temperature range.
• Enable function allows resetting all switches to the off state, facilitating the stacking of multiple devices.

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix matches the required configuration. The '-T1' suffix indicates tape and reel packaging, while '-E3' confirms lead-free and RoHS compliance. Confirm the specific package type corresponds to the design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring an 8:1 multiplexing configuration with low on-resistance and fast switching speeds. Ensure the system voltage does not exceed the absolute maximum ratings of 44 V between V+ and V-. Verify that the thermal dissipation capabilities of the TSSOP package are sufficient for the intended power load.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG4xx series of high-performance CMOS analog multiplexers. It is designed using a 44 V silicon-gate CMOS process which provides extended voltage ratings and latchup protection. The DG408 serves as the single-ended counterpart to the differential DG409 within this product family.
