PI5A23159UEX

Overview

The PI5A23159UEX is a low voltage dual single-pole double-throw (SPDT) analog switch manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and supports signal voltages up to 5.5V. The device features an on-resistance as low as 0.7Ω at 4.5V supply, with a maximum of 1.1Ω under specified conditions. It provides -70dB off-isolation and crosstalk isolation at 1MHz, alongside a 150MHz bandwidth. The component is housed in a 10-pin MSOP package.

Feature Summary

Dual SPDT architecture enabling independent switching control for two channels
Low on-resistance performance optimized for minimal signal loss across wide voltage ranges
High off-isolation and crosstalk suppression ensuring signal integrity in dense layouts
Rail-to-rail signal handling capability compatible with various logic families

Applications

Portable consumer electronics requiring low power consumption
Audio and video signal routing systems
Communication equipment utilizing high-frequency data transmission
Battery-powered devices needing efficient power management

Procurement Notes

Verify the specific ordering suffix 'UEX' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm RoHS 3 compliance status matches current regulatory requirements for your target market. Ensure the 10-pin MSOP footprint aligns precisely with your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require low voltage operation below standard 5V thresholds while maintaining high signal fidelity. Consider the 0.7Ω typical on-resistance for applications demanding minimal voltage drop. Evaluate the 150MHz bandwidth against your highest frequency signal requirements to ensure adequate performance margins.

Part Context

This part belongs to Diodes Incorporated's family of low voltage analog switches designed for portable applications. It complements other series components offering similar switching capabilities but tailored for different voltage levels or channel counts. The MSOP package allows for compact board space utilization in modern handheld devices.

Replacement Considerations

Direct pin-compatible substitutes are not explicitly listed in the provided documentation. Verify functional equivalence regarding on-resistance, leakage current, and package dimensions if considering alternative manufacturers. Consult official cross-reference guides for potential upgrades within the same product family.

FAQ

What is the maximum operating voltage for the PI5A23159UEX?

The recommended operating supply voltage (VCC) ranges from 1.65V to 5.5V.

How does the on-resistance vary with supply voltage?

On-resistance increases as supply voltage decreases; it is typically 0.7Ω at 4.5V and rises to approximately 2.8Ω at 1.65V under specific load conditions.
