SA555DR TI Precision Timer | 8-SOIC | 4.5V-16V, 100kHz

Product Overview

The SA555DR 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 SA555DR is specified for operation from 4.5V to 16V, with a maximum output frequency of 100kHz. It is housed in an 8-pin SOIC package, making it suitable for space-constrained applications.
