Product speciﬁcation

LCD direct/duplex driver with

I2C-bus interface

PCF8577C

Notes

1. Typical conditions: VDD = 5 V; Tamb =25 °C.

2. Resets all logic when VDD < VPOR.

3. Periodically sampled, not 100% tested.

4. Outputs measured one at a time.

5. Outputs measured one at a time; VDD = 5 V; Iload = 100 µA.
