DG408LEDQ-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408LEDQ-GE3 is an eight-channel single-ended analog multiplexer from Vishay Siliconix, housed in a 16-pin TSSOP package. It operates on single supplies of 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device connects one of eight inputs to a common output via a 3-bit binary address (A0, A1, A2). Key electrical parameters include a maximum on-resistance of 92 Ω at 3 V and 27 Ω at 12 V, with a typical value of 17 Ω. Switching times are 73 ns for turn-on and 46 ns for turn-off. Leakage current is limited to 1 nA maximum, and power consumption is 6 μA maximum.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features break-before-make switching action to prevent momentary crosstalk between adjacent channels.
• Includes an enable function that resets all switches to the off state, facilitating the stacking of multiple devices.
• Control inputs and address lines are TTL compatible across the full specified operating temperature range.
• Utilizes an internal regulator to power logic circuits, reducing overall device power consumption.

Analog Switches, Multiplexers, Demultiplexers Applications

• Automatic test equipment
• Data acquisition systems
• Medical and healthcare systems
• Battery powered systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and compliance status. The 'Q' suffix indicates a TSSOP-16 package, while 'Y' denotes SOIC-16. The 'GE3' suffix confirms lead-free and RoHS compliance. Ensure the required quantity matches the standard tube packaging of 360 units for this specific variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an eight-channel single-ended multiplexing solution is required within a 16-pin surface-mount footprint. Consider the DG409LE if differential signal routing is needed instead. Verify that the supply voltage range aligns with the application's single or dual rail requirements to ensure optimal on-resistance performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408LE family, which offers enhanced performance over previous generations through lower on-resistance and improved leakage limits. It maintains pin-for-pin compatibility with legacy parts like the DG408 and DG508, allowing for direct upgrades in existing designs without requiring schematic modifications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG408LEDQ-T1-GE3 provides the same functionality in a tape and reel format. DG408LEDY-GE3 serves as a package alternative using the SOIC-16 form factor. Both variants maintain identical electrical specifications and pinouts for design flexibility.
