SA555D TI Precision Timer | 8-SOIC | Supply Voltage 4.5V-16V, Timing Accuracy ±1%

Product Overview

The SA555D 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 SA555D is designed to operate over a wide supply voltage range from 4.5V to 16V, with timing from microseconds to hours. It features a temperature stability of 0.005% per °C and a timing accuracy of ±1%. The device is offered in an 8-pin SOIC package, making it suitable for space-constrained applications.
