LM555/NE555/SA555
Single Timer
Features
· · · · · High Current Drive Capability (200mA) Adjustable Duty Cycle Temperature Stability of 0.005%/°C Timing From µSec to Hours Turn off Time Less Than 2µSec
Description Description
The LM555/NE555/SA555 is a highly stable controller capable of producing accurate timing pulses. With a monostable operation, the time delay is controlled by one external resistor and one capacitor. With an astable operation, the frequency and duty cycle are accurately controlled by two external resistors and one capacitor.

Notes: 1. When the output is high, the supply current is typically 1mA less than at VCC = 5V. 2. Tested at VCC = 5.0V and VCC = 15V. 3. This will determine the maximum value of RA + RB for 15V operation, the max. total R = 20M, and for 5V operation, the max. total R = 6.7M. 4. These parameters, although guaranteed, are not 100% tested in production.
