Features & Applications

The PCA9557BS,118 is a 8 bit silicon CMOS circuit which provides parallel input/output expansion for SMBus and I2C-bus applications.

It consists of an 8-bit input /output port register, and an I2C-bus/SMBus interface with low current consumption and a high-impedance open-drain output.

Features:

  • Lower voltage, higher performance migration path for the PCA9556
  • 8 general purpose input/output expander/collector
  • Input/output configuration register
  • Active HIGH polarity inversion register
  • I2C-bus and SMBus interface logic
  • Internal power-on reset
  • Noise filter on SCL/SDA inputs
  • Active LOW reset input
  • 3 address pins allowing up to 8 devices on the I2C-bus/SMBus
  • High-impedance open-drain on IO0
  • No glitch on power-up
  • Power-up with all channels configured as inputs
  • Low standby current
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5 V tolerant inputs/outputs
  • 0 kHz to 400 kHz clock frequency

Applications:

  • Industrial
  • Automotive
