NA555DR TI Precision Timer | 8-SOIC | 4.5V-16V, 100kHz

Product Overview

The NA555DR from Texas Instruments is a precision timing circuit capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The NA555DR is offered in an 8-pin SOIC package, making it suitable for space-constrained applications.

產品概述

NA555DR 是德州儀器 (TI) 生產的高精度定時器電路，能夠產生準確的時間延遲或振盪。在單穩態模式下，定時時間由單個外部電阻和電容網絡控制。在無穩態模式下，頻率和佔空比可通過兩個外部電阻和一個外部電容獨立控制。NA555DR 採用 8 引腳 SOIC 封裝，適合空間受限的應用。
