NJM556
DUAL TIMER
■
GENERAL DESCRIPTION
The
NJM556
dual monolithic timing circuit is a highly stable
controller capable of producing accurate 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 capacitor.
Terminal 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.
