Description
The SMSNE555 is a highly stable timer IC that can be operated in astable mode and monostable mode.
For monostable mode: time delay is controlled by one external and one capacitor.
For stable mode: frequency and duty cycle are accurately controlled with two external resistors and one capacitor.
Features
• High current driver capability (=200mA)
• Adjustable duty cycle
• timing form sec to hours
• turn off time less than 2 sec
Applications
• Precision timing
• Pulse generation
• Time delay generation
