SNJ54LS373FK TI Latches | Octal D-Type | 3-State Output, 4.5V-5.5V

Product Overview

The SNJ54LS373FK is a high-performance octal D-type transparent latch with 3-state outputs, manufactured by Texas Instruments. It is designed for use in systems requiring high-speed data storage and bus-oriented applications. The device features eight latches with individual D-type inputs and common enable (LE) and output enable (OE) controls. When LE is high, the Q outputs follow the D inputs; when LE goes low, the data is latched. The OE pin controls the 3-state outputs, allowing multiple devices to share a common bus. The SNJ54LS373FK is specified for operation over the full military temperature range (-55°C to +125°C) and is available in a 20-pin ceramic flatpack (FK) package.

產品概述

SNJ54LS373FK 是一款高性能八路 D 型透明鎖存器，具有三態輸出，由德州儀器（TI）製造。該器件專為需要高速數據存儲和總線應用的系統而設計。它包含八個獨立的 D 型輸入鎖存器，以及公共的鎖存使能（LE）和輸出使能（OE）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 引腳控制三態輸出，允許多個器件共享公共總線。SNJ54LS373FK 的額定工作溫度範圍為完整的軍用溫度範圍（-55°C 至 +125°C），採用 20 引腳陶瓷扁平封裝（FK）。
