DG451EY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG451EY-T1-E3 is a high-voltage quad SPST CMOS analog switch in a 16-pin narrow SOIC package. It features four independently selectable switches with a typical on-resistance of 4 Ω and flatness of 0.2 Ω. The device supports dual supplies from ±5 V to ±15 V or a single supply of 12 V to 36 V, handling continuous currents up to 100 mA. Key electrical parameters include a maximum turn-on time of 118 ns, turn-off time of 97 ns at ±15 V, charge injection of 22 pC, and off-isolation of -60 dB at 1 MHz. Operating temperature ranges from -40 °C to 125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• TTL/CMOS compatible digital inputs with defined logic thresholds for reliable control
• ESD protection rated at 2 kV (HBM) to safeguard against electrostatic discharge events

Analog Switches, Multiplexers, Demultiplexers Applications

• Audio and video signal switching
• Precision automatic test equipment
• Relay replacement circuits
• Sample and hold systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EY' confirms the 16-pin narrow SOIC package variant rather than the TSSOP option. Confirm RoHS compliance status as specified in the datasheet documentation. Ensure the component meets the required operating temperature range of -40 °C to 125 °C for your specific application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage handling up to 44 V is required alongside low on-resistance for signal integrity. The 16-pin narrow SOIC package is suitable for applications where board space allows for standard surface mount footprints. Consider the 118 ns switching speed adequate for the target frequency range and ensure the 100 mA continuous current rating exceeds peak load requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG45x series which includes DG451 (NC), DG452 (NO), and DG453 (mixed). It is pin-compatible with the DG411, DG412, and DG413 series, allowing for potential direct replacements if logic polarity or configuration differences are managed. The EY suffix specifically denotes the SOIC-16 package format within this family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG451EY-T1-E3 is pin-compatible with the DG411EY-T1-E3. Verify logic input inversion differences between NC and NO configurations when substituting with other members of the DG45x or DG41x families.
