DG411LDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411LDQ-T1-E3 is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features a maximum drain-source on-resistance of 33 Ω and typical turn-on/turn-off times of 50 ns and 35 ns, respectively. It utilizes BiCMOS fabrication technology for improved performance over standard counterparts. The component is housed in a 16-pin Thin-Shrink Small Outline Package (TSSOP) with an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging and 'E3' denotes lead-free/RoHS compliance when sourcing. Confirm the 'D' suffix corresponds to the TSSOP-16 package variant. Check current availability status as manufacturing lifecycles may vary. Ensure the logic control requirements match the DG411L truth table specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage operation between 2.7 V and 12 V. It serves as a pin-for-pin compatible upgrade to the standard DG411 series with enhanced speed and lower resistance. Verify that the required on-resistance and leakage current limits fall within the specified ranges for the intended supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411L family, which includes companion devices DG412L and DG413L. These are low-voltage CMOS switches designed as improvements over the industry-standard DG411 series. The 'L' designation specifically indicates the low-voltage capability and BiCMOS process technology used for superior dynamic performance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include DG411DY-T1-E3 and DG411DQ-T1-E3. Note that these alternatives may have different on-resistance values or power dissipation ratings compared to the DG411LDQ-T1-E3.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic control behavior of the DG411L?

The DG411L responds to opposite control logic compared to the DG412L. A logic '0' turns the switch ON, while a logic '1' turns it OFF.

Does the DG411L support break-before-make switching?

No, the DG411L does not feature break-before-make switching. This function is only available in the DG413L variant.

What is the maximum power dissipation for the TSSOP package?

The maximum power dissipation for the 16-pin TSSOP package is 450 mW, with a derating factor of 7 mW/°C above 75 °C.
