Description

The PCA9554D is an 8-bit parallel Input/output (GPIO) Expander for I²C-bus/SMBus applications and were developed to enhance the NXP Semiconductors family of I²C-bus I/O expanders. The improvements include higher drive capability, 5V I/O tolerance, lower supply current, individual I/O configuration, 400kHz clock frequency. The I/O expander provides a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans and so on. It consists of an 8-bit configuration register (input or output selection); 8-bit input port register, 8-bit output port register and an 8-bit polarity inversion register (active HIGH or active LOW operation). The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding input port or output port register. The polarity of the read register can be inverted with the polarity inversion register.
Polarity inversion register
Active low interrupt output
Low standby current consumption
Noise filter on SCL/SDA input
No glitch on power-up
Internal power-ON reset
Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
