PI4ULS3V502XVEX

Translators, Level Shifters Overview

The PI4ULS3V502 is a 2-bit configurable dual-supply autosensing bidirectional level translator designed for push-pull applications. It operates with VCCA ranging from 0.85V to 2.7V and VCCB from 1.35V to 3.6V, allowing independent supply configurations where VCCA may be greater than, equal to, or less than VCCB. The device guarantees a data rate of up to 280 Mb/s at 15 pF load and supports 30 pF capacitive drive capability. It features low bit-to-skew, overvoltage tolerant I/O pins, non-preferential power-up sequencing, and power-off protection.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead-free green material declarations directly with Diodes Incorporated or authorized distributors before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing between logic families requiring distinct voltage rails that do not follow standard step-down constraints. Ensure input drivers can provide sufficient peak current for the auto-sense architecture. Verify that the application environment remains within the specified -40°C to +85°C operating temperature range.

Translators, Level Shifters Part Context

This part belongs to the PI4ULS3V series of ultra-low voltage level translators manufactured by Diodes Incorporated (formerly Pericom). These components are engineered for portable electronics requiring efficient voltage translation between different power domains while minimizing board space through compact packaging solutions.

Translators, Level Shifters Replacement Considerations

Consult official substitution guides for equivalent 2-channel bi-directional translators. Verify pin compatibility and electrical characteristics match requirements before replacing.
