13 AC CHARACTERISTICS

VDD = 1.8 to 5.5 V; VSS =0V; VLCD = 2.2 − 6.5 V; Tamb = −40 to +85 °C; unless otherwise speciﬁed.

Note

1. All timing values are valid within the operating supply voltage and ambient temperature range and are referenced to

VIL and VIH with an input voltage swing of VSS to VDD.
