SN74AHC373RKSR TI Octal D-Type Latch | 20-VQFN (2.5x4.5) | 8-bit, 2V to 5.5V

Product Overview

The SN74AHC373RKSR from Texas Instruments is an octal transparent D-type latch with 3-state outputs. It is designed for 2-V to 5.5-V VCC operation, making it ideal for a wide range of applications. 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 is low, the Q outputs are latched. The OE input, when high, places the outputs in a high-impedance state. This device is housed in a compact 20-VQFN (2.5x4.5) package, offering space-saving benefits for modern electronics.

產品概述

SN74AHC373RKSR 是德州儀器（TI）生產的八路透明 D 型鎖存器，帶三態輸出。該器件支持 2 V 至 5.5 V 的電源電壓範圍，適用於多種應用。它包含八個獨立的 D 型輸入和 Q 輸出鎖存器，由鎖存使能（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 為低電平時，Q 輸出保持鎖存狀態。OE 為高電平時，輸出處於高阻抗狀態。該器件採用緊湊的 20-VQFN（2.5x4.5）封裝，節省電路板空間。
