10 / 20 page ![]() Electrical characteristics STUSB03E 10/20 Table 13. AC electrical characteristics (VIF = 3.6V, VBUS = 5V unless otherwise noted; TA = 25°C.) (Note 6) Note 1. Exceeding the absolute maximum rating may damage the device. Note 2. The device is not guaranteed to function outside its operating rating. Note 3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. Note 4. Specification applies to the following pins: SUS, SPD, RCV, CON, RCV, VP, VM, OE#. Note 5. Characterized specification(s), but not production tested. Note 6. All AC parameters guaranteed by design but not production tested. Symbol Parameter Test Conditions Min. Typ. Max.
