1. Astable mode design information
a. Unit-to-unit transfer-voltage variations
The following analysis presents worst-case variations from unit-to-unit as a function of transfer-voltage (VTR) shift for free
running (astable) operation.
Values for tA are:
thus if tA = 4,40 RtCt is used, the maximum variation will be (+ 7,0%; 0,0%) at 10 V.
typ. : VTR = 0,5 VDD;tA = 4,40 RtCt
VDD = 5 or 10 V
min. : VTR = 0,3 VDD;tA = 4,71 RtCt
max.: VTR = 0,7 VDD;tA = 4,71 RtCt
VDD = 15 V
min. : VTR =4 V;
tA = 4,84 RtCt
max.: VTR = 11 V;
tA = 4,84 RtCt
