NJM555
TIMER
■ GENERAL DESCRIPTION
The NJM555 monolithic timing circuit is a highly stable controller
capable of producing accruate time delays or oscillation. In the time
delay mode, delay time is precisely controlled by only two external
parts : a resistor and a capacitor. For operation as an oscillator, both
the free running frequency and the duty cycle are accurately controlled
by two external resistors and a capacitor.
Terminals are provided for triggering and resetting. The circuit will
trigger and reset on falling waveforms. The output can source or sink
up to 200mA or drive TTL circuits.
