PCA9518 - Expandable Five-Channel I2C HUB

General Description

The PCA9518 is an expandable five-channel bidirectional buffer for I2C and SMBus applications.

The I2C protocol requires a maximum bus capacitance of 400 pF, which is derived from the number of devices on the I2C bus and the bus length.

Key Features

  • 1 Expandable Five-Channel Bidirectional Buffer.
  • 400-kHz Fast I2C Bus.
  • Operating VCC Range of 3 V to 3.6 V.
  • 5-V Tolerant I2C and Enable Input Pins to Support Mixed-Mode Signal Operation.
  • Active-High Individual Repeater Enable Inputs.
  • Open-Drain Input/Outputs.
  • Lockup-Free Operation.
  • Supports Multiple Masters.
  • Powered-Off High-Impedance I2C Pins.
  • I2C Bus and SMBus Compatible.
  • Latchup Performance Excee.
