DG412LEDQ-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412LEDQ-GE3 is a monolithic quad single-pole-single-throw analog switch from Vishay Siliconix, housed in a 16-lead TSSOP package. It features an on-resistance of 16 Ω and operates on single supplies from 3 V to 16 V or dual supplies from ±3 V to ±8 V. The device exhibits low parasitic capacitance (15 pF on-state) and charge injection under 8 pC. Switching times are fast, with turn-on at 16 ns and turn-off at 9 ns. It supports TTL and CMOS logic levels and functions within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'DQ' confirms the 16-lead TSSOP tube packaging configuration. Confirm RoHS compliance status as indicated by the 'GE3' suffix. Ensure the logic sense matches system requirements, as this part responds to opposite logic levels relative to other members of the DG41xLE family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch requires operation at lower supply voltages down to 3 V. The DG412LE variant is appropriate for designs requiring inverted logic control signals compared to standard positive-logic switches. Verify that the 16 Ω on-resistance meets the voltage drop requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG411LE/DG412LE/DG413LE series designed for low-voltage applications. While sharing identical electrical specifications regarding resistance and speed, the DG412LE differs functionally only in its response to opposite logic levels compared to the DG411LE. The DG413LE offers mixed normally open and closed configurations.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the logic control of the DG412LE differ from the DG411LE?

The DG411LE and DG412LE differ only in that they respond to opposite logic levels. A logic high turns the DG411LE on, whereas it turns the DG412LE off.

What is the maximum analog signal range for the DG412LEDQ-GE3?

The analog signal range extends from the negative supply rail to the positive supply rail, supporting single supplies up to 16 V or dual supplies up to ±8 V.

Does the DG412LE support break-before-make switching?

No, break-before-make switching is a feature specific to the DG413LE variant, which contains two normally open and two normally closed switches.
