15 AC CHARACTERISTICS
VDD = 2.5 to 6.0 V; VSS =0V; VLCD =VDD 3.5VtoVDD 9V;Tamb = 40 °Cto+85 °C; unless otherwise specied.
Notes
1. VDD = 5.0 V.
2. 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.
