SN74ALS533ADW TI Latches | 20-SOIC | 8-Bit D-Type, Transparent

Product Overview

The SN74ALS533ADW from Texas Instruments is a high-performance octal D-type transparent latch with 3-state outputs. It is designed for use in bus-oriented systems where data must be latched and held while the bus is used for other operations. The device features an 8-bit latch with a latch enable (LE) input and an output enable (OE) input. When LE is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched to the data that was present at the D inputs at the time LE transitioned low. The OE input, when high, places the outputs in a high-impedance state, allowing for bus sharing. The device is fabricated using advanced Schottky barrier diode technology for high speed and low power consumption.

產品概述

SN74ALS533ADW 是德州儀器 (TI) 生產的高性能八路 D 型透明鎖存器，帶三態輸出。它專為匯流排系統設計，可在匯流排用於其他操作時鎖存並保持數據。該器件具有 8 位鎖存器，帶鎖存使能 (LE) 輸入和輸出使能 (OE) 輸入。當 LE 為高電平時，Q 輸出跟隨數據 (D) 輸入；當 LE 為低電平時，Q 輸出鎖存在 LE 轉為低電平時 D 輸入的數據。OE 輸入為高電平時，輸出處於高阻抗狀態，允許匯流排共享。該器件採用先進的肖特基勢壘二極管技術，具有高速和低功耗的特點。
