SN74ALS573CDW TI Latches | 20-SOIC | 8-Bit D-Type, 3-State Output

Product Overview

The SN74ALS573CDW is a high-performance octal D-type transparent latch with 3-state outputs from Texas Instruments. It is designed for use in bus-oriented systems where data must be latched and held while the bus is used for other purposes. The device features eight latches with individual D-type inputs and Q outputs, controlled by a latch enable (LE) and output enable (OE) input. When LE is high, the Q outputs follow the D inputs; when LE goes low, the data is latched. The OE input controls the 3-state outputs, allowing multiple devices to share a common bus. The SN74ALS573CDW is fabricated using advanced Schottky technology for high speed and low power consumption.

產品概述

SN74ALS573CDW 是德州儀器（TI）生產的一款高性能八路 D 型透明鎖存器，帶有三態輸出。它專為匯流排導向系統設計，在匯流排用於其他用途時，數據可以被鎖存並保持。該器件包含八個鎖存器，每個鎖存器具有獨立的 D 型輸入和 Q 輸出，由鎖存使能（LE）和輸出使能（OE）輸入控制。當 LE 為高電平時，Q 輸出跟隨 D 輸入；當 LE 變為低電平時，數據被鎖存。OE 輸入控制三態輸出，允許多個器件共享同一匯流排。SN74ALS573CDW 採用先進的肖特基工藝製造，具有高速和低功耗的特點。
