This highly versatile logic IC contains four independent line drivers, each equipped with its own active-low output-enable (OE) pin. While it operates on a standard 1.65V to 3.6V supply, its inputs are fully 5V-tolerant. This makes it an incredibly useful tool for safely stepping down 5V logic signals from external sensors or receivers to safe 3.3V levels for STM32 or ESP32 processors without the need for complex level-shifting circuits.\u003c\/p\u003e\n\u003cp\u003eIn the realm of custom drone Flight Controllers and professional DIY electronics, this chip is an unsung hero. It is frequently used to isolate SPI buses (allowing multiple gyros or OSD chips to share the same data lines), buffer high-speed UART telemetry, and protect delicate MCU pins from accidental external shorts. The 3-state output capability allows you to easily disconnect signals from a shared data bus, preventing data collisions. Housed in a compact TSSOP-14 package, it saves PCB space while remaining relatively easy to hand-solder during repairs.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eFour Independent Buffers:\u003c\/b\u003e 4 individual channels with separate output-enable (OE) controls for ultimate signal flexibility.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003e5V-Tolerant Inputs:\u003c\/b\u003e Safely accepts 5V logic signals even when the chip itself is powered by 3.3V, making it a perfect unidirectional level shifter.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh-Speed Operation:\u003c\/b\u003e Extremely low propagation delay ensures flawless performance on fast SPI or UART communication lines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMCU Protection:\u003c\/b\u003e Acts as a physical electrical barrier between external peripheral connections and your expensive flight controller processor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e SN74LVC125APWR\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIC Type:\u003c\/b\u003e Quad Buffer \/ Line Driver (3-State)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSupply Voltage (Vcc):\u003c\/b\u003e 1.65V – 3.6V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eInput Voltage Tolerance:\u003c\/b\u003e Up to 5.5V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMax Output Current:\u003c\/b\u003e ±24 mA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Type:\u003c\/b\u003e TSSOP-14 (SMD\/SMT)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RC-LIFE","offers":[{"title":"Default Title","offer_id":54259853525330,"sku":null,"price":3.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1065\/8067\/2850\/files\/OPA4323.jpg?v=1786706828","url":"https:\/\/rc-life.com\/products\/sn74lvc125apwr-quadruple-bus-buffer-with-3-state-outputs-tssop-14","provider":"rc-life","version":"1.0","type":"link"}
