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.

Note: 1. For the HA17555/PS,
This value applies up to Ta = 50°C; at temperatures above this, 8.3mW/°C derating should be
applied.
For the HA17555F/FP,
This value applies up to Ta = 25°C; at temperatures above this, 3.85mW/°C derating should be
applied.
