XS3A2467PWJ

Overview

The Nexperia XS3A2467 is a dual low-ohmic double-pole double-throw analog switch designed for use as an analog or digital multiplexer/demultiplexer. It contains four switches, each with two independent inputs/outputs (nY0 and nY1) and a common input/output (nZ). The device operates on a wide supply voltage range from 1.4 V to 4.3 V. It features very low ON resistance, typically 0.5 Ω at VCC = 2.7 V and 4.3 V, and 1.6 Ω at VCC = 1.4 V. The component supports high current handling of 350 mA continuous current under a 3.3 V supply. It includes Schmitt trigger action at the digital inputs for tolerance to slow signal transitions and allows signals up to VCC to be transmitted bidirectionally.

Feature Summary

• Very low ON resistance ensures minimal attenuation and distortion of transmitted signals across various supply voltages.
• Break-before-make switching mechanism prevents short circuits during state transitions.
• Control logic accepts voltages above the supply voltage, enabling direct interfacing with 1.8 V logic levels in 3.3 V applications without level translation.
• High noise immunity and robust ESD protection exceeding standard industrial requirements.

Applications

• Appliances
• Communication Systems
• Medical Equipment
• Analog Sensor Monitoring
• Audio Routing/Switching

Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the TSSOP16 plastic thin shrink small outline package aligns with PCB layout constraints. Ensure design compliance with absolute maximum ratings to prevent permanent damage. Cross-reference the latest product data sheet revision for any updates to specifications or pin configurations before finalizing procurement.

Selection Notes

Select this component when low signal distortion and high current capacity are critical within a compact footprint. The ability to drive the control inputs with 1.8 V logic while switching higher voltage signals simplifies system architecture by eliminating external level shifters. Evaluate the ON resistance flatness requirements against the specific signal amplitude conditions expected in the application circuit.

Part Context

This dual SPDT analog switch belongs to Nexperia's portfolio of low-power CMOS switching solutions. It is housed in a SOT403-1 (TSSOP16) package, providing a space-efficient solution for dense board layouts. The device is specified for operation from -40 °C to +125 °C, making it suitable for demanding industrial and consumer environments requiring reliable signal routing.

Replacement Considerations

Consult official Nexperia documentation for verified substitute part numbers. Ensure any replacement maintains compatible pinout, voltage ratings, and ON resistance characteristics to guarantee functional equivalence without redesigning the host circuitry.
