DESCRIPTION
The Contek NE558 is a monolithic quadtimer which can be used to produce four entirely independent timing functions. The highly stable, general purpose controller can be used in a monostable mode to produce accurate time delays.

FEATURES
* Wide supply voltage: Vcc= 4.5V~15V
* 100mA output current per-section
* Edge trigger without coupling capacitor
* Time period equals RC
* Output independent

APPLICATIONS
* Precision timing
* Quad one-shot
* Timing delay generation
* Sequential timing.
