Product Summary
The ha17555ps is a Precision Timer. The ha17555ps is ICs designed for accurate time delays or oscillations. It provides both of trigger terminal and reset terminal in order to enable a wide scope of application including Mono Multi Vibrator and Astable Multi Vibrator, and the number of external components is fewer. Further, it’s compatible with NE555 of singnetics. The applications of the ha17555ps include Delay Time Generator (Mono Multi Vibrator), Pulse Generator (Astable Multi Vibrator), Pulse Width Modulator, Pulse Location Modulator and Miss Pulse Detector.
