HA17555 Series
Precision Timer
ADE-204-064 (Z)
Rev. 0
Dec. 2000
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 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.
