PI5A4157CEX

Overview

The PI5A4157CEX is a single-pole double-throw (SPDT) analog switch manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 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. It offers fast transition speeds, with turn-on times as low as 9ns at 5.0V, and provides a high bandwidth of 150MHz. The component is housed in a 6-pin SOT-363 package and functions within an extended industrial temperature range of -40°C to +85°C.

Feature Summary

Ultra-low on-resistance for minimal signal loss
Rail-to-rail signal handling capability
Break-before-make switching to prevent signal disruption
Control input tolerant of voltages independent of the supply

Applications

Cell phones
PDAs
Portable instrumentation
Battery-powered communications equipment
Computer peripherals

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and reel configuration. Ensure that the procurement channel is authorized to maintain product integrity and warranty coverage. Cross-reference the manufacturer part number with the datasheet to validate compatibility with system requirements before finalizing orders.

Selection Notes

Select this component when designing circuits requiring low latency and high bandwidth for analog signal routing. The wide operating voltage range makes it suitable for various power supply architectures. Consider the thermal dissipation limits and package size constraints during layout planning to ensure reliable operation across the specified temperature range.

Part Context

This component belongs to the PI5A series of low-voltage analog switches produced by Diodes Incorporated. The series is designed for bus and analog applications where signal integrity and speed are critical. The PI5A4157 variant specifically addresses needs for compact, high-performance switching in portable electronic devices.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family or from other manufacturers. Verify that any substitute matches the electrical characteristics, particularly on-resistance and bandwidth, to ensure seamless integration without redesigning the circuit board.

FAQ

What is the maximum voltage tolerance for the control input?

The control input has a minimum overvoltage tolerance of 5.5V, allowing it to interface directly with baseband processor general purpose I/Os even when the control voltage differs from the VCC supply.

How does the device prevent signal disruption during switching?

The PI5A4157 utilizes break-before-make switching technology, which ensures that both switches are not enabled simultaneously, thereby eliminating signal disruption during the transition.
