Product speciﬁcation

LCD direct/duplex driver with

I2C-bus interface

PCF8577C

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

Note

1. Reduce by 7.7 mW/K when Tamb >60 °C.

HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe it is

desirable to take normal precautions appropriate to handling MOS devices. Advice can be found in Data Handbook IC12

under

“Handling MOS Devices”.
