Overview
The PCA9558PW,118, produced by NXP USA Inc., is a highly integrated, multi-function device designed to enhance the functionality and efficiency of various electronic systems. This component combines a 5-bit multiplexed/1-bit latched 6-bit I2C-bus/SMBus EEPROM DIP switch, an 8-bit I/O expander, and a 2-kbit serial EEPROM into a single chip. This integration reduces component count and board space requirements, making it particularly useful in computer, server, and telecom/networking applications.

Key Features
- 5-bit multiplexed/1-bit latched 6-bit I2C-bus/SMBus EEPROM DIP switch, allowing for digital information selection and replacement of traditional DIP switches or jumpers.
- 8-bit I/O expander for controlling, monitoring, or collecting remote information, with the ability to read or store data via I2C-bus/SMBus.
- 2-kbit serial EEPROM for storing information such as card identification or revision/maintenance history, accessible via I2C-bus/SMBus.
- One address pin, enabling up to two devices on the same I2C-bus or SMBus.
- Active LOW override input to force all MUX_OUTx outputs to logic 0 and active LOW reset input with internal pull-up for the eight I/O pins.
- 5 V tolerant open-drain MUX_OUTx and NON_MUXED_OUT outputs and I/O pins, power-up default as outputs.
- ESD protection exceeding 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101.
