GENERAL DESCRIPTION

The PCF2105 integrated circuit is similar to the PCF2114x (described in the “PCF2116 family” data sheet) but does not contain the high voltage generator of that device.

Furthermore, a fast I2C-bus interface (400 kHz) is provided.

The PCF2105 is optimized for chip-on-glass applications.
