Description

Description:

HA17555 Series are ICs designed for accurate time delays or oscillations.HA17555 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.

Application

· Delay Time Generator (Mono Multi Vibrator)
· Pulse Generator (Astable Multi Vibrator)
· Pulse Width Modulator
· Pulse Location Modulator
· Miss Pulse Detector

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. See notes on SOP Package Usage in Reliability section.
