The PCA9557PW,112 from NXP Semiconductors is an 8-bit general purpose input/output expander designed for SMBus and I2C-bus applications. It offers a flexible interface logic with configurable input/output registers and an active HIGH polarity inversion register. This device operates within a voltage range of 2.3 V to 5.5 V and supports clock frequencies up to 400 kHz.
The PCA9557PW,112 features an active LOW reset input and an internal power-on reset. It is housed in a 16-TSSOP package, suitable for surface mount applications. The device provides 8 general purpose input/output channels and has an open-drain output on IO0. Its noise filter on SCL/SDA inputs enhances signal integrity.
This IO expander is designed for applications requiring parallel input/output expansion. It has a low standby current and is 5 V tolerant on its inputs and outputs. The power-on reset initializes registers to their default state, and all channels are configured as inputs upon power-up.
