Overview
The PI5A4157CEX-1516 is a 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 features an ultra-low on-resistance of 0.8Ω typical at 3.0V. The device supports rail-to-rail signal ranges and includes control input overvoltage tolerance up to 5.5V. Key electrical parameters include a maximum turn-on time of 25ns, a maximum turn-off time of 35ns, and a -3dB bandwidth of 150MHz. It functions across an extended industrial temperature range from -40°C to +85°C.
Feature Summary
- Ultra-low on-resistance for minimal signal loss in analog paths
- Rail-to-rail signal handling capability across the full supply range
- Break-before-make switching logic to prevent simultaneous channel conduction
- Control input tolerant to 5.5V independent of the VCC supply level
Applications
- Cell phones and mobile handsets
- Portable instrumentation devices
- Battery-powered communications equipment
- Computer peripherals
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Confirm RoHS compliance status and environmental declarations directly with the manufacturer or authorized distributors before finalizing procurement orders.
Selection Notes
Select this component when low on-resistance and high bandwidth are required for SPDT signal routing. Ensure the design accommodates the specified operating voltage range and that the control logic levels align with the defined VIH and VIL thresholds for reliable switching operation.
Part Context
This part belongs to the PI5A4157 family of low-voltage SPDT analog switches. The base model offers identical electrical performance characteristics, while the specific suffix indicates the packaging configuration and tape-and-reel format intended for automated surface-mount assembly processes.
Replacement Considerations
PI5A4157TAEX: Identical electrical specifications packaged in SOT23-6. PI5A4157ZUEX: Identical electrical specifications packaged in UDFN-6 (1mm x 1mm). Verify pinout compatibility and thermal dissipation requirements when substituting packages.
