DESCRIPTION

The M51841 P /M5E555P monolithic timing circuit is a highly

stable controller capable of producing accurate time delays,

or oscillation. Additional terminals are provided for triggering

or resetting, if desired. In the time delay mode, the time is

precisely controlled by one external resistor and capacitor.

For a stable operation as an oscillator, both the free running

frequency and the duty cycle are accurately controlled by

two external resistors and capacitor.

The circuit will trigger and reset on falling waveforms,

and the output structure can source or sink up to 200mA or

drive TTL circuits.
