DG452EQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG452EQ-T1-E3 is a high voltage monolithic quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin TSSOP package. It features four independently selectable switches with a typical on-resistance of 4 Ω and an on-resistance flatness of 0.2 Ω. The device supports dual supplies from ±5 V to ±15 V or a single supply from 12 V to 36 V, accommodating a maximum supply differential of 44 V. It operates within a temperature range of -40 °C to 125 °C, offering fast switching speeds with turn-on times up to 118 ns and turn-off times up to 97 ns at full temperature limits.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against the official Vishay datasheet Document Number 74470 to confirm specifications. Ensure the ordering suffix matches the required package type and temperature rating. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG452EQ-T1-E3 when normally open switch logic is required, as it differs from the DG451 only by inverted control input polarity. Confirm that the application requires a 16-pin TSSOP surface-mount package. Verify that the system voltage does not exceed the 44 V absolute maximum rating across the supply pins.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG451/DG452/DG453 family of high voltage analog switches manufactured by Vishay Siliconix. The DG452 variant specifically provides four normally open switches, distinguishing it from the DG451 which offers normally closed switches. All three variants share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG452EQ-T1-E3 is pin-compatible with the DG412EY-T1-E3 and DG412EQ-T1-E3. Designers replacing older DG211 or DG212 devices can utilize this component as a drop-in upgrade due to shared pin configurations.
