DG469EY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG469EY-T1-E3 is a high voltage single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates with dual supplies ranging from ±4.5 V to ±15 V or a single supply up to 12 V, supporting a maximum supply differential of 44 V. The device features a typical on-resistance of 3.6 Ω and a maximum of 6 Ω at room temperature. It provides fast switching speeds with turn-on times up to 166 ns and turn-off times up to 108 ns under standard test conditions. Packaged in an 8-pin Narrow SOIC, it supports an operating temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'E3' confirms RoHS compliance and lead-free status as per Vishay specifications. Confirm the package type matches the required surface mount footprint. Ensure the component meets the specific temperature grade requirements for the intended application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage handling and low distortion are critical. The DG469 lacks an enable pin; use the DG470 variant if a safe state or mute function is required. Verify that the power dissipation limits accommodate the thermal constraints of the target PCB layout.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG469/DG470 series of high voltage SPDT analog switches. It shares identical electrical characteristics with the DG470, except the DG470 includes an additional enable input pin for controlling the switch state independently.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG470EY-T1-E3 is the direct functional equivalent with an added enable pin. Other high voltage SPDT switches may require circuit redesign due to differences in pinout or control logic.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the DG469 have an enable pin?

No, the DG469 does not have an enable pin. The DG470 variant includes an enable input for high impedance mode control.

What is the maximum supply voltage difference?

The absolute maximum rating for the voltage difference between V+ and V- is 44 V.

How does the switch handle channel transitions?

It guarantees break-before-make switching action to prevent momentary shorting when switching between the normally open and normally closed contacts.
