SN74LS258BD TI Multiplexer | 16-SOIC | Quad 2-to-1, 3-State Outputs

Product Overview

The SN74LS258BD is a quad 2-to-1 data selector/multiplexer with 3-state outputs from Texas Instruments. It features Schottky-clamped TTL logic for high speed and low power consumption. The device selects one of two 4-bit data sources (A or B) based on the select input (S) and provides the selected data at the outputs when the output enable (OE) is low. When OE is high, the outputs are in a high-impedance state, allowing multiple devices to share a common bus. The SN74LS258BD is housed in a 16-pin SOIC package, ideal for space-constrained applications.

產品概述

SN74LS258BD 是德州儀器推出的四路2選1數據選擇器/多路復用器，具有三態輸出。它採用肖特基鉗位TTL邏輯，實現高速和低功耗。器件根據選擇輸入（S）從兩個4位數據源（A或B）中選擇一個，並在輸出使能（OE）為低時提供所選數據。當OE為高時，輸出處於高阻抗狀態，允許多個器件共享公共總線。SN74LS258BD 採用16引腳SOIC封裝，適合空間受限的應用。
