PCAL6408A Datasheet (NXP Semiconductors) - 8-bit I2C-bus/SMBus I/O expander

PCAL6408A, 8-bit I2C-bus/SMBus I/O expander

The PCAL6408A is an 8-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface.

NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powe
