12. Dynamic characteristics
Table 10. Dynamic characteristics
VDD = 2.5 V to 6 V; VSS = 0 V; Tamb = ï€40 ï‚°C to 85 ï‚°C; unless otherwise specified. All the timing values are valid within the
operating supply voltage and ambient temperature range and refer to VIL and VIH with an input voltage swing of VSS to VDD.
