PCA9617ADP

The PCA9617A can accommodate 540 pF on either side of the device at 1 MHz and up to 4000 pF at lower speeds.

The EN pin in the PCA9617A integrated circuit is used to enable or disable the drivers under system control. It is active HIGH with thresholds referenced to V CC(B) and has an internal pull-up to V CC(B) to maintain the device active unless the user chooses to disable the repeater. The EN pin should not change state during an I2C-bus operation to prevent issues with bus operation.

The voltage range for the bus port B drivers in the PCA9617A integrated circuit is 2.2 V to 5.5 V. This range allows for static level offset in port B drivers, accommodating smaller voltage swings of lower voltage logic systems. The adjustable voltage bus port A drivers in the PCA9617A eliminate the static offset voltage.
