IC 555

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 Stable 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
