PI5A4764GAEX

Overview

The PI5A4764GAEX is a 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 features an on-resistance of 0.6Ω at 2.7V. The device supports rail-to-rail signal ranges and includes shunt switches connected to ground to dissipate capacitance, reducing audio popping sounds. It utilizes break-before-make switching logic to prevent simultaneous switch activation. The component is housed in a 10-ball CSP package and functions over an extended industrial temperature range from –40°C to +85°C.

Feature Summary

• Dual SPDT configuration with low on-resistance for bus and analog applications
• Shunt switches connected to ground to reduce audio clicking and popping during source switching
• Break-before-make switching mechanism prevents signal disruption during transitions
• Control input tolerates drive signals up to 6.0V independent of the supply voltage

Applications

• Speaker headset switching
• Audio and video signal routing
• Power routing and relay replacement
• Portable instrumentation and computer peripherals

Procurement Notes

Verify the specific ordering suffix 'GAEX' against official manufacturer documentation to confirm packaging details such as tape and reel specifications. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the part number with current datasheets to validate any potential revisions or updates to the manufacturing process.

Selection Notes

Select this component when designing circuits requiring dual high-bandwidth analog switching with minimal signal distortion. The low on-resistance and wide supply voltage range make it suitable for portable battery-powered devices. Consider the 10-ball CSP package size for space-constrained layouts. Verify that the control input voltage levels align with the system logic requirements, noting the tolerance up to 6.0V.

Part Context

This component belongs to the PI5A4764 series of small package, dual SPDT audio clickless analog switches. Originally developed by Pericom Semiconductor, the product line was acquired by Diodes Incorporated. The series is characterized by its CMOS technology optimized for low power consumption and high performance in mobile and consumer electronics applications.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Generic replacements may not match the specific shunt switch functionality or the exact on-resistance characteristics required for clickless audio operation.
