SINGLE TIMER: The LM555/I is a highly stable controller capable of producing accurate
timing pulses. With monostable operation, the time delay is controlled
by one external and one capacitor. With astable operation, the frequency
and duty cycle are accurately controlled with two external resistors and
one capacitor.
FEATURES:
· High Current Drive Capability (= 200mA)
· Adjustable Duty Cycle
· Temperature Stability of 0.005%/°C
· Timing From mSec To Hours
· Turn Off Time Less Than 2mSec
