Detailed description
I2C Expander – Reliability Without Limits
The PCA9554PW,118 is a GPIO expander from NXP that expands the capabilities of any I²C/SMBus system with exceptional reliability. With 8 independently configurable I/O lines and a clock frequency up to 400 kHz, this 16-pin TSSOP16 package component doesn’t compromise. Need more inputs for sensors, buttons, or LEDs? The PCA9554PW,118 handles this quickly, without overloading your microcontroller.
Capabilities That Surpass Standards – PCA9554PW,118 in Practice
The device offers a supply voltage from 2.3 V to 5.5 V and full 5 V tolerance on inputs/outputs, making it highly flexible for industrial and consumer applications. Onboard are configuration registers, polarity inversion, and state reading – all accessible from the master. Plus, an open-drain interrupt output ensures no state change goes unnoticed.
