SN74AHC125QWBQARQ1 TI Quad Bus Buffer | 14-WQFN (3x2.5) | 2V-5.5V, 8mA

Product Overview

The SN74AHC125QWBQARQ1 is a quad bus buffer gate with 3-state outputs from Texas Instruments, designed for automotive applications. It operates over a wide supply voltage range of 2V to 5.5V, making it suitable for interfacing with both 3.3V and 5V logic families. The device features four independent buffer gates with active-low output enable (OE) inputs. When OE is low, the output is enabled; when high, the output is in high-impedance state. This allows multiple outputs to be connected to a common bus without conflict. The device is offered in a compact 14-WQFN (3x2.5mm) package, ideal for space-constrained designs.

產品概述

SN74AHC125QWBQARQ1 是德州儀器（TI）推出的四路總線緩衝器門電路，具有三態輸出，專為汽車應用設計。它支持 2V 至 5.5V 的寬電源電壓範圍，適合與 3.3V 和 5V 邏輯系列接口。該器件包含四個獨立的緩衝器門，每個門帶有低電平有效的輸出使能（OE）輸入。當 OE 為低電平時，輸出使能；當 OE 為高電平時，輸出處於高阻抗狀態。這允許多個輸出連接到公共總線而不發生衝突。器件採用緊湊的 14-WQFN（3x2.5mm）封裝，適合空間受限的設計。
