DG401DJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401DJ-E3 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Semiconductors. It operates within a supply voltage range of 13 V to 36 V for single supplies or ±7 V to ±22 V for dual supplies. The device features a maximum on-resistance of 45 Ohms, with a typical charge injection of 60 pC and off-state leakage current of 500 pA. Switching times are specified at a maximum of 150 ns for turn-on and 100 ns for turn-off. It is housed in a 16-pin PDIP package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration providing independent signal path control
• CMOS technology ensuring low power consumption and high input impedance
• High breakdown voltage capability suitable for diverse signal levels
• Low charge injection for accurate signal switching

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring isolated signal routing
• Programmable gain amplifiers and instrumentation circuits
• Sample-and-hold applications in signal processing chains
• Multiplexed sensor interfaces

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance status through official manufacturer documentation before integration. Confirm that the PDIP-16 package dimensions match the target PCB footprint requirements. Ensure the supply voltage limits align with the system design to prevent device damage during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch with moderate speed and low on-resistance is required. Compare against the DG401DY variant if surface-mount assembly is preferred over through-hole mounting. Verify that the 45 Ohm on-resistance meets the signal integrity requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG40x series of enhanced analog switches from Vishay Siliconix. The series is characterized by improved operating voltage ranges and lower leakage compared to earlier generations. The DG401 specifically provides two independent SPST channels in a standard 16-pin DIP format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG401BDY-T1-E3 serves as a functional equivalent offering identical electrical specifications but utilizes a surface-mount SOIC-16 package instead of the through-hole PDIP-16 form factor.
