[1] To avoid drawing V
CC
current out of terminal Z, when switch current flows into terminals Yn, the voltage drop across the bidirectional switch must not
exceed 0.4 V. If the switch current flows into terminal Z, no V
CC
current will flow out of terminals Yn. In this case there is no limit for the voltage drop across
the switch, but the voltages at Yn and Z may not exceed V
CC
or V

derates linearly with 8 mW/K.
For SSOP20 packages: above 60 °C the value of P
tot
derates linearly with 5.5 mW/K.
