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.
