PCF8576C

Universal LCD driver for low multiplex rates

11. Dynamic characteristics

[1]

fclk < 125 kHz, I2C-bus maximum transmission speed is derated.

[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.

Table 16.

Dynamic characteristics

VDD = 1.8 V to 5.5 V; VSS = 0 V; VLCD = 2.5 V to 6.5 V; Tamb = −40 °C to +85 °C; unless otherwise specified.
