PCF85133

Universal LCD driver for low multiplex rates

10. Static characteristics

[1]

LCD outputs are open-circuit; inputs at VSS or VDD; external clock with 50 % duty factor; I2C-bus inactive.

[2]

Not tested, design speciﬁcation only.

[3]

Outputs measured individually and sequentially.

Table 16.

Static 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.
