JSMSEMI NE555DR-JSM

NE555DR is a bipolar IC capable of generating high-precision timing pulses. It consists of four internal circuit blocks: a threshold comparator, a trigger comparator, an RS flip-flop, and an output stage. With a minimal number of external resistors and capacitors, it can be configured as a timing trigger circuit, PWM circuit, audio oscillator, and more. Widely used in toys, traffic signaling, automation control, and other applications.
