PI3A27518Q2ZDWEX

Overview

The PI3A27518Q2ZDWEX is a 6-channel, 1:2 multiplexer/demultiplexer manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 3.6V and supports rail-to-rail signal passing. The device features break-before-make switching to prevent simultaneous switch activation. Key electrical parameters include an on-resistance of 5.2Ω maximum at +3.3V, a 3dB bandwidth of 380MHz, and off-isolation of -66dB at 10MHz. It is housed in a 24-pin V-QFN4040-24 package.

Feature Summary

Supports AEC-Q100 Grade 2 qualification for automotive environments
Break-before-make switching prevents signal disruption during transitions
Rail-to-rail signal range accommodates wide analog input voltages
High off-isolation and crosstalk rejection reduce signal distortion

Applications

SD-SDIO and MMC two-port MUX
qSPI two-port MUX
Analog bus switching applications

Procurement Notes

Verify the component against the official datasheet DS43570 Rev 3-2. Confirm that the ordering suffix matches the specific requirements for automotive compliance, lead-free status, and tape-and-reel packaging configuration before finalizing procurement.

Selection Notes

Select this component when designing systems requiring low propagation delay and high bandwidth for multiple signal paths. Ensure the operating temperature range aligns with the specified -40°C to +105°C limits for reliable performance in demanding environments.

Part Context

This part belongs to the PI3A27518Q family of high-bandwidth multiplexers. It is specifically designed for applications requiring robust signal routing with minimal interference. The Q2 suffix indicates AEC-Q100 Grade 2 qualification, making it suitable for automotive use cases requiring strict change control.

Replacement Considerations

Consult the manufacturer's documentation for verified substitute part numbers. Cross-reference pin configurations and electrical specifications to ensure compatibility with existing circuit designs.
