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 circui.

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. ■ PACKAGE OUTLINE N JM556D N JM556M ■ FEATURES ● Dual Timer Circuits ● Less number of External Components ● Package Outline ● Bipolar Technology DIP14, DMP14 ■ PIN CONFIGURATION N JM556D N JM556M ■ EQUIVALENT CIRCUIT (1/2 Shown) PIN FUNCTION 1.
