概述
Description
PI3B3253QEX is a part from Renesas/Pericom’s PI3B3xxx family. It’s a 3-channel bidirectional bus switch/level translator used to buffer and translate signals between two voltage domains. Key ideas: three pass-gate channels with auto-direction sensing, a common enable (tri-states when disabled), and two supply rails to support level shifting (e.g., 1.8–2.5V on one side and 3.3V on the other). The “QEX” suffix denotes the package variant (typically a QFN with exposed pad); exact pin count and package type should be verified in the datasheet. Applications: UI/MPU peripherals, memory/IO expansion, any scenario needing simple, low-cost level shifting and buffering without external buffers. For precise electrical specs, operating rails, and package details, consult the official PI3B3253QEX datasheet.
Equivalent
I can’t provide exact equivalents without the device function. PI3B3253QEX is a Pericom PI3B-series part; please share its function (e.g., bus switch, buffer, translator), supply voltage, and package or attach the datasheet. Then I can give cross-references from TI, NXP, Onsemi, Renesas, etc., with substitute part numbers.
