NOTES:
1. The junction temperature must be kept below 125°C for the D package and below 150°C for the FE, N and F packages. At ambient temperaturesabove 25°C, where this limit would be derated by the following factors:
D package 160°C/W
FE package 150°C/W
N package 100°C/W
F package 105°C/W


Description

The AS555 is a highly stable controller capable of producing accurate time delays, or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The AS555 may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.
