10.2 Dynamic characteristics
[1]
Event counter mode only.
[2]
All timing values are valid within the operating supply voltage, ambient temperature range, reference to VIL and VIH and with an input
voltage swing of VSS to VDD.
Table 8.
Dynamic characteristics
VDD = 2.5 V to 6.0 V; VSS = 0 V; Tamb = 40 °C to +85 °C unless otherwise specified.
