IC 555

Description

IC 555 timer is a one of the most widely used IC in electronics and is used in various electronic circuits for its robust and stable properties. It works as square-wave form generator with duty cycle varying from 50% to 100%, Oscillator and can also provide time delay in circuits. The 555 timer got its name from the three 5k ohm resistor connected in a voltage-divider pattern. Features: Timing from microseconds to hours Operates in both Astable and Monostable modes Replaces two 555 timers Adjustable duty cycle Output can source or sink 200mA Output and supply TTL compatible Temperature stability better than 0.005% per ˚C Normally on and normally off output Low turn off time, less than 2μs Application: Precision timing Pulse generation Sequential timing Traffic light control Time delay generation Pulse width and pulse position modulation Linear ramp generator Industrial controls
