CD54HCT139F TI Decoder/Demultiplexer | 2-to-4 Line | High-Speed CMOS, Dual

Product Overview

The CD54HCT139F is a high-speed CMOS dual 2-to-4 line decoder/demultiplexer from Texas Instruments. It is designed for memory decoding and data routing applications requiring low power dissipation and high noise immunity. The device features two independent decoders, each accepting two binary inputs (A0, A1) and providing four mutually exclusive active-low outputs (Y0–Y3). An active-low enable input (G) controls each decoder. When the enable is high, all outputs are forced high regardless of the select inputs. The CD54HCT139F is fabricated using silicon gate CMOS technology, which ensures balanced propagation delays and high drive capability. It is available in a ceramic dual-in-line package (CDIP) and operates over the full military temperature range of -55°C to +125°C.

產品概述

CD54HCT139F 是德州儀器 (TI) 生產的高速 CMOS 雙路 2 線至 4 線解碼器/多路分配器。它專為需要低功耗和高抗噪能力的存儲器解碼及數據路由應用而設計。該器件包含兩個獨立的解碼器，每個解碼器接收兩個二進制輸入 (A0, A1)，並提供四個互斥的低電平有效輸出 (Y0–Y3)。每個解碼器都有一個低電平有效的使能輸入 (G)。當使能為高電平時，無論選擇輸入如何，所有輸出均被強制為高電平。CD54HCT139F 採用硅柵 CMOS 工藝製造，確保了平衡的傳播延遲和高驅動能力。它採用陶瓷雙列直插封裝 (CDIP)，工作溫度範圍為 -55°C 至 +125°C，滿足軍用級要求。
