DG418BDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG418BDQ-T1-E3 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a ±15 V dual supply or up to 36 V single supply, providing an analog signal range of ±15 V. The device features a maximum on-resistance of 25 Ω and supports a continuous current of 30 mA. Switching performance includes a turn-on time of 89 ns and a turn-off time of 80 ns at room temperature. It utilizes a TSSOP-16 package configuration in this specific variant, though the datasheet lists SOIC-8 and MSOP-8 for the series. The component operates across a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-voltage silicon gate (HVSG) process construction ensures superior switching performance and prevents latchup via an epitaxial layer.
• Bidirectional conduction capability allows equal signal flow in both directions when on, while blocking up to the power supply level when off.
• TTL and CMOS compatible logic control simplifies interfacing with standard digital systems.

Analog Switches, Multiplexers, Demultiplexers Applications

• Precision test equipment
• Battery powered industrial and military systems
• Sample-and-hold circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact package type against the ordering suffix, as the datasheet specifies SOIC-8 and MSOP-8 for the DG418B series. Confirm RoHS compliance status through official documentation. Validate that the intended operating voltage does not exceed the absolute maximum ratings to ensure device reliability.
