[1] To avoid drawing VCC 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 VCC 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 VCC or VEE.

[2] For SOT163-1 (SO20) package: Ptot derates linearly with 12.3 mW/K above 109 °C.

For SOT339-1 (SSOP20) package: Ptot derates linearly with 10.0 mW/K above 100 °C.

For SOT360-1 (TSSOP20) package: Ptot derates linearly with 10.0 mW/K above 100 °C.
