New Japan Radio Co.,Ltd. www.njr.com NJM555 TIMER GENERAL DESCRIPTION PACKAGE OUTLINE 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 NJM555D NJM555M 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.
