[1] The supply current value is essentially independent of the TRIGGER, THRESHOLD and RESET voltages.
[2] Astable timing is calculated using the following equation:
f = (---R----A----+-1---.-32---8-R----B---)--C---
The components are defined in Figure 15.
[3] RA, RB = 1 kΩ to 100 kΩ; C = 0.1 µF; 5 V < VDD < 15 V
[4] Parameter is not 100 % tested.
