CD40257BMT TI Multiplexer | 16-SOIC | 4-Channel, 2:1, 3V-18V

Product Overview

The CD40257BMT from Texas Instruments is a high-performance CMOS quad 2-input multiplexer with common select and enable logic. It is designed for general-purpose digital multiplexing applications requiring low power consumption and wide supply voltage range. The device features four independent multiplexer channels, each with two data inputs (A and B) and one output (Y). A common SELECT input determines which data input is routed to the output, and a common ENABLE input forces all outputs to a high-impedance state when low. The CD40257BMT is offered in a 16-pin SOIC package, making it suitable for space-constrained designs.

產品概述

CD40257BMT 是德州儀器 (TI) 生產的高性能 CMOS 四路 2 選 1 多路復用器，具有公共選擇和使能邏輯。該器件適用於需要低功耗和寬電源電壓範圍的通用數字多路復用應用。它包含四個獨立的多路復用通道，每個通道有兩個數據輸入（A 和 B）和一個輸出（Y）。公共 SELECT 輸入決定哪個數據輸入被路由到輸出，公共 ENABLE 輸入在低電平時將所有輸出置為高阻抗狀態。CD40257BMT 採用 16 引腳 SOIC 封裝，適合空間受限的設計。
