PCA9554DGVR +BOM

Advanced semiconductor device protects against electrostatic discharge and voltage spikes

PCA9554DGVR Information

General Description

Furthermore, users should note that the PCA9554DGVR is pin-to-pin and I2C address compatible with the PCF8574. However, some software modifications may be necessary to fully utilize the enhancements offered by the PCA9554 over its predecessor. The PCA9554DGVR and PCA9554A are nearly identical, with the main distinction being their fixed I2C addresses. This allows for the possibility of incorporating up to 16 of these devices (eight of each type) on the same I2C/SMBus network, providing expanded capabilities for complex systems
