Features & Applications
The PCA9554 and PCA9554A are 16-pin CMOS devices that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion 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, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.

Features:

  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5 V tolerant I/Os
  • Polarity Inversion register
  • Active LOW interrupt output
  • Low standby current
  • Noise filter on SCL/SDA inputs
  • No glitch on power-up
  • Internal power-on reset
  • 8 I/O pins which default to 8 inputs
  • 0 Hz to 400 kHz clock frequency
