PI5A4158ZAEX

Overview

The PI5A4158ZAEX is a dual high-bandwidth, fast single-pole double-throw (SPDT) CMOS analog switch manufactured by Diodes Incorporated. It operates within a wide supply voltage range of 1.65V to 5.5V and features an ultra-low on-resistance of 0.8Ω typical at 3.0V VCC. The device supports rail-to-rail signal ranges and includes control input overvoltage tolerance up to 5.5V minimum. Key electrical parameters include a maximum on-resistance of 1.1Ω at 4.5V, a bandwidth of 150 MHz, and transition speeds of 12ns at 5.0V. It functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

Break-before-make switching mechanism prevents simultaneous switch enablement to eliminate signal disruption during transitions.
Control inputs are independent of the supply voltage, allowing direct interface with baseband processor general-purpose I/Os even when control voltage is lower than VCC.
Ultra-low quiescent current consumption ensures efficient operation in mobile handset applications.
Rail-to-rail signal range capability supports broad analog signal handling requirements.

Applications

Cell phones
PDAs
Portable instrumentation
Battery powered communications
Computer peripherals

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distribution channels or certified distributors. Confirm package marking matches TDFN-12 1x3 specifications and check for lead-free green compliance documentation. Ensure storage conditions remain within specified limits to maintain reliability before soldering.

Selection Notes

Select this component for designs requiring low latency bus switching or analog signal routing within the 1.65V to 5.5V supply domain. Evaluate thermal dissipation capabilities against the 350mW power rating at +85°C ambient temperature. Consider the 12-pin TDFN footprint constraints during PCB layout planning to ensure adequate thermal relief and mechanical stability.

Part Context

This part belongs to the PI5A4158 family of low-voltage SPDT analog switches produced by Diodes Incorporated. The ZAEX suffix indicates a lead-free, green compliant version packaged in a tape and reel format suitable for automated surface-mount assembly processes.
