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.


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.
