PCA9617A: Level-Translating I2C-Bus / SMBus Repeater

The PCA9617A is an I2C-bus repeater that provides level shifting between low voltage (0.8 V to 5.5 V) and higher voltage (2.2 V to 5.5 V) for Fast-Mode Plus (Fm+) I2C-bus or SMBus applications.

Features
  • Voltage level translation from 0.8 V to 5.5 V and from 2.2 V to 5.5 V
  • Footprint and functional replacement for PCA9517A at Fast-mode speeds
  • 2 channel, bidirectional buffer isolates capacitance and allows 540 pF on either side of the device
Benefits
  • Flexible enough to work in most systems using up to 5.5V
  • Easy to design into new systems or to replace PCA9517A
  • Able to drive large loads at high speeds
Applications
  • Servers
  • DDR4
