SN74HC594DWR TI Shift Register | 16-SOIC | 8-bit, Serial-In Parallel-Out

Product Overview

The SN74HC594DWR from Texas Instruments is a high-performance 8-bit shift register with output latches and 3-state outputs. It features a serial input (SER), a shift clock (SRCLK), a storage register clock (RCLK), and an output enable (OE). Data is shifted into the shift register on the rising edge of SRCLK and transferred to the storage register on the rising edge of RCLK. The 3-state outputs are enabled when OE is low. This device operates over a wide supply voltage range of 2 V to 6 V and is characterized for operation from -40°C to +85°C. The SN74HC594DWR is ideal for applications requiring serial-to-parallel data conversion, such as LED displays, relay drivers, and microcontroller port expansion.

產品概述

SN74HC594DWR 是德州儀器（TI）推出的一款高性能8位移位寄存器，具有輸出鎖存器和三態輸出。它包含串行輸入（SER）、移位時鐘（SRCLK）、存儲寄存器時鐘（RCLK）和輸出使能（OE）。數據在 SRCLK 上升沿移入移位寄存器，並在 RCLK 上升沿傳輸到存儲寄存器。當 OE 為低電平時，三態輸出被使能。該器件在 2 V 至 6 V 的寬電源電壓範圍內工作，並在 -40°C 至 +85°C 的溫度範圍內進行特性化。SN74HC594DWR 非常適合需要串行到並行數據轉換的應用，例如 LED 顯示屏、繼電器驅動器和微控制器端口擴展。
