PIN I/O DESCRIPTION
NAME NO.
VCCA 1 Supply A-side supply voltage (0.9 V to 5.5 V)
SCLA 2 I/O Serial clock bus, A side.
SDAA 3 I/O Serial data bus, A side.
GND 4 Supply Supply ground
EN 5 Input Active-high repeater enable input
SDAB 6 I/O Serial data bus, B side. Connect to VCCB through a pull-up resistor.
SCLB 7 I/O Serial clock bus, B side. Connect to VCCB through a pull-up resistor.
VCCB 8 Supply B-side and device supply voltage (2.7 V to 5.5 V)
Thermal Attach Pad - - Thermal Attach Pad is not electrically connected and it is recommended to be attached to GND for best thermal performance. This is for the RVH package only.
