High Voltage I/O (HVIO) DC Parameters

Table 22 shows the HVIO DC electrical operating conditions. The parameters are guaranteed per the

operating ranges in Table 11, unless otherwise noted.

1 To maintain a valid level, the transitioning edge of the input must sustain a constant slew rate (monotonic) from the current DC

level through to the target DC level, VIL or VIH. Monotonic input transition time is from 0.1 ns to 1 s. VIL and VIH do not apply

when hysteresis is enabled.

Hysteresis of 350 mV is guaranteed over all operating conditions when hysteresis is enabled.
