Overview
The PI3A27518ZDEX is a high-bandwidth, 6-channel multiplexer/demultiplexer manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 1.65V to 3.6V and features rail-to-rail signal handling capabilities. The device provides a typical on-resistance of 5Ω at +3.3V and supports a signal bandwidth of 380MHz. Key electrical parameters include a maximum propagation delay of 30ns, off-isolation of -66dB at 10MHz, and crosstalk rejection of -60dB at 10MHz. It utilizes CMOS technology for low power consumption and includes break-before-make switching logic. The component is housed in a 24-pin TQFN package with dimensions of 4mm x 4mm.
Feature Summary
- Supports wide operating voltage range from 1.65V to 3.6V with rail-to-rail signal passing
- Features break-before-make switching to prevent simultaneous switch activation and eliminate signal disruption
- Provides high off-isolation and crosstalk rejection to reduce signal distortion
- Includes ESD protection rated at 2.5kV (HBM) for enhanced reliability
Applications
- SD-SDIO and MMC two-port multiplexing
- qSPI two-port multiplexing
- Audio and video signal routing
Procurement Notes
Verify the specific ordering suffix against official documentation before procurement. The 'E' suffix indicates lead-free and green compliance, while the 'X' suffix denotes tape and reel packaging. Confirm that the selected variant matches the required packaging format and environmental standards for your manufacturing process.
Selection Notes
Select this component when designing systems requiring multi-port signal routing within a compact footprint. Ensure the application voltage falls between 1.65V and 3.6V. Consider the 380MHz bandwidth and low capacitance characteristics if high-frequency analog or digital signals are being switched. Verify thermal requirements for the TQFN package in dense layouts.
Part Context
This part belongs to the PI3A27518 series of high-bandwidth analog switches. It is designed for bus and analog applications where low propagation delay and minimal signal distortion are critical. The device integrates six independent channels into a single small form factor, making it suitable for portable electronics and interface circuits.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the 24-pin TQFN package and compatible pinout. Verify that alternative components meet the same voltage, bandwidth, and isolation specifications.
