1) _{TCA 305 only}
2) _{Values in parenthesis apply to TCA 355 only}
3) _{Operation at voltages less than 5 V (between approx. 2.5 and 5 V) is possible, if VREF is connected to VS. In}
this case VREF is no longer internally stabilized. Additionally, the pin "turn-on delay" is to be applied as follows:
If no turn-on delay is needed, this pin has to be connected to VS. If, however, a turn-on delay is required, the
charge current for DD has to be adjusted with an external resistor between this pin and VS (recommended
value 390 k^Ω).
