NXP PCA9554ABS3118 GPIO Expander
The PCA9554 and PCA9554A are 8-bit CMOS I/O port expanders that provide configurable, low-power, GPIO expansion for I2C-bus and SMBus applications. These devices feature higher drive capability, 5 V I/O tolerance, individual I/O configuration, and interrupt signaling when input states change. They include registers for configuration, input, output, and polarity inversion, enabling flexible operation. Suitable for adding extra I/O in systems with sensors, LEDs, or switches, they operate across a voltage range of 2.3 V to 5.5 V, offering reliable, low standby current, and varied package options including SO16, SSOP16/20, TSSOP16, HVQFN16, and bare die.
