Electrical characteristics

This section summarizes the operating and measurement conditions, and the DC and AC characteristics of the

device. The parameters in the DC and AC characteristic tables that follow are derived from tests performed under

the measurement conditions summarized in the relevant tables. Users should check that the operating conditions

in their circuit match the measurement conditions when relying on the quoted parameters.

Note:

Stresses listed above may cause permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those indicated in the operational sections of the

specification is not implied.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

4.2

DC and AC characteristics

TA = −40 to 105 °C (for the 3.3 V voltage range only) and TA = −25 to 85 °C (for the 1.8 V and 3.3 V voltage

ranges).

The voltage (VPS) on all inputs or outputs must not exceed one of the two authorized ranges: 1.8 V ±10% or 3.3 V

±10%.
