Overview
The PI5A3167CCEX is a single-pole single-throw (SPST) 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 VCC. The device provides rail-to-rail signal range capability and includes power-off protection on I/O pins. It supports fast transition speeds, achieving 2ns turn-on time at 5.0V, with a high bandwidth of 200MHz. The component is housed in a 5-pin SC-70 package and functions within an extended industrial temperature range of -40°C to +85°C.

Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the package type and reel configuration. Ensure that the selected variant matches the required lead-free and green specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.
Selection Notes
Select this component when low on-resistance and wide supply voltage compatibility are required for analog signal routing. Consider the 200MHz bandwidth and fast transition times for high-speed bus applications. Verify that the control logic levels align with the system's baseband processor outputs. Confirm that the SC-70 package dimensions fit the available PCB footprint constraints.
Part Context
This component belongs to the PI5A3167 series of low-voltage SPST analog switches. The 'C' designation indicates the specific electrical characteristics and performance metrics defined in the datasheet. The 'EX' suffix denotes the tape and reel packaging format. This series is designed for mobile handset applications requiring direct interface with general-purpose I/Os.
