8-Channel, I²C Bus Switch

NXP's 8-Channel, I²C bus switch features an ultra-low voltage operation

Image of NXP's 8-Channel, I2C-bus SwitchNXP's PCA9848 is an ultra-low voltage, octal-bidirectional translating switch controlled via the I2C bus. The SCL / SDA upstream pair fans out to eight downstream pairs or channels. Any or all SCx / SDx channels can be selected, determined by the programmable control register. This feature allows multiple devices with the same I2C bus address to reside on the same bus. The switch device can also separate a heavily-loaded I2C bus into separate bus segments, eliminating the need for a bus buffer.

Benefits
  • Ultra-low voltage operation (down to 0.8 V) to interface with next-generation CPUs
  • 1-of-8 bidirectional translating switch
  • Active LOW reset input
  • Fm+ I2C bus interface logic compatible with SMBus standards
  • Two address pins allowing up to sixteen devices on the I2C bus
