SN74AS158DR TI Multiplexer | 16-SOIC | 4x2:1, Single Supply 4.5V-5.5V

Product Overview

The SN74AS158DR is a high-speed quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments. It features Schottky-clamped transistors for high performance and is designed for applications requiring fast propagation delays and low power consumption. The device selects one of two 4-bit data sources under control of a common select input (S). The outputs are inverting and provide the complement of the selected data. A strobe input (G) is provided for enabling the outputs; when G is high, all outputs are forced low (inactive). The SN74AS158DR is offered in a 16-pin SOIC package, making it suitable for space-constrained designs.

產品概述

SN74AS158DR 是德州儀器（TI）生產的高速四路2選1數據選擇器/多路復用器。它採用肖特基箝位晶體管以實現高性能，適用於需要快速傳播延遲和低功耗的應用。該器件在公共選擇輸入（S）的控制下，從兩個4位數據源中選擇一個。輸出為反相，提供所選數據的補碼。提供選通輸入（G）用於使能輸出；當G為高電平時，所有輸出被強制為低電平（無效）。SN74AS158DR 採用16引腳SOIC封裝，適合空間受限的設計。
