SINGLE TIMER

DESCRIPTION
The C555 astable and monostable timing circuit is a highly
stable controller capable of producing accurate time delays, or
oscillation.

FEATURES
* Timing from microseconds through hours
* High speed operation – 500kHz
* Wide operation supply voltage range – 2 to 18 voltages
* Low Supply Current -0.2mA
* Operates in both astable and monostable modes
* High output source/sink driver can drive TTL / CMOS
* Adjustable duty cycle
