SN74HC595DWR TI Shift Register | 16-SOIC | 8-bit, Serial-In Parallel-Out

Product Overview

The SN74HC595DWR from Texas Instruments is an 8-bit serial-in, parallel-out shift register with a storage register and 3-state output. It operates over a wide voltage range of 2V to 6V, making it suitable for various digital applications. The device features a serial input (SER), a shift register clock (SRCLK), a storage register clock (RCLK), and an output enable (OE) input. Data is shifted into the 8-bit 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. The SN74HC595DWR is available in a 16-pin SOIC package, offering a compact solution for expanding digital outputs.

產品概述

SN74HC595DWR 是德州儀器（TI）生產的8位串行輸入、並行輸出移位寄存器，帶有存儲寄存器和三態輸出。該器件在2V至6V的寬電壓範圍內工作，適用於各種數字應用。它具有串行輸入（SER）、移位寄存器時鐘（SRCLK）、存儲寄存器時鐘（RCLK）和輸出使能（OE）輸入。數據在SRCLK的上升沿移入8位移位寄存器，並在RCLK的上升沿傳輸到存儲寄存器。當OE為低電平時，三態輸出使能。SN74HC595DWR採用16引腳SOIC封裝，為擴展數字輸出提供了緊湊的解決方案。
