SN74HC126DBR TI Buffer/Driver | 14-SSOP | 2V-6V, 7.8mA

Product Overview

The SN74HC126DBR is a high-speed quad bus buffer gate with 3-state outputs from Texas Instruments. It operates over a wide supply voltage range of 2V to 6V, making it suitable for a variety of logic-level applications. The device features four independent buffer gates with non-inverting outputs, each with its own output enable input. When the output enable (OE) input is high, the output is enabled; when low, the output is in a high-impedance state. This allows for bus-oriented applications where multiple outputs can share a common line. The SN74HC126DBR is offered in a compact 14-pin SSOP package, ideal for space-constrained designs.

產品概述

SN74HC126DBR 是德州儀器（TI）生產的高速四路總線緩衝閘，具有三態輸出。該器件可在 2V 至 6V 的寬電源電壓範圍內工作，適用於各種邏輯電平應用。它包含四個獨立的非反相緩衝閘，每個閘都有自己的輸出使能輸入。當輸出使能（OE）輸入為高電平時，輸出被啟用；為低電平時，輸出處於高阻抗狀態。這使得它適用於總線導向的應用，其中多個輸出可以共享一條公共線路。SN74HC126DBR 採用緊湊的 14 引腳 SSOP 封裝，非常適合空間受限的設計。
