Description

HA17555 Series are 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.

Features

•  Mono multi vibrator can be constructed with one resistor and one capacitor.
•  Astable multi vibrator can be constructed with two resistors and one capacitor.
•  Delay time can be established widely from several μ seconds to several hours.
•  Pulse Duty can be controlled.
•  The maximum value of both sink current and source current is 200mA.
•  Direct connection of output to TTL is possible.
•  Temperature/delay time ratio is 50 ppm/°C (typ).
•  Output is normally in the on and off states.
