DC Electrical Characteristics
All typical values are at 25°C unless otherwise specified.
Notes:
3. Measured by the voltage drop between Dn, HSD, and Dn pins at the indicated current through the switch.
On resistance is determined by the lower of the voltage on the two ports.
4. Guaranteed by characterization.
AC Electrical Characteristics
All typical values are for VCC = 3.3V are at 25°C unless otherwise specified.
Note:
5. Guaranteed by characterization.
