DG9425DQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9425DQ-T1-E3 is a low voltage, dual supply, low on-resistance quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It utilizes BiCMOS wafer fabrication technology to operate on single supplies from 3 V to 12 V or dual supplies of ±3 V to ±6 V. The device features fast switching times with a typical turn-on time of 42 ns and turn-off time of 28 ns at 12 V single supply. It offers an on-resistance as low as 1.7 Ω, minimal insertion loss with a -3 dB bandwidth of 190 MHz, and excellent crosstalk performance of -77 dB at 1 MHz. The component operates within a temperature range of -40 °C to +85 °C and is housed in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Ensure that the required operating voltage and signal ranges align with the absolute maximum ratings defined in the datasheet. Confirm availability status directly with authorized distributors, as production lifecycles may change without prior notice.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high-speed switching are critical for audio or video signal paths. The DG9425 responds to opposite control logic compared to the DG9424; verify truth table requirements against system design. Consider the 16-pin TSSOP footprint for PCB layout constraints and ensure power dissipation limits are respected under maximum load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG9424/DG9425/DG9426 family of low voltage precision analog switches. While functionally similar regarding electrical characteristics, the DG9425 differs from the DG9424 in its digital control logic polarity. Both devices share the same physical package and pinout configuration, facilitating potential design flexibility within the same product line.
