HA17555 General 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.

HA17555 Maximum Ratings

Item	Symbol	HA17555PS/FP	HA17555/F	Unit
Supply voltage	V_CC	18	18	V
Discharge current	I_T	200	200	mA
Output source current	Isource	200	200	mA
Output sink current	Isink	200	200	mA
Power dissipation*¹	P_T	600/385	600/385	mW
Operating temperature	Topr	20 to +75	20 to +70	°C
Storage temperature	Tstg	55 to +125	55 to +125	°C

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.

HA17555 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.

HA17555 Typical Application
