Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 VCCA Supply A-side supply voltage (0.9 V to 5.5 V)
2 SCLA Input/Output Serial clock bus, A-side. Connect to VCCA through a pull-up resistor. If unused, connect directly to ground.
3 SDAA Input/Output Serial data bus, A-side. Connect to VCCA through a pull-up resistor. If unused, connect directly to ground.
4 GND Ground Ground
5 EN Input Active-high repeater enable input
6 SDAB Input/Output Serial data bus, B-side. Connect to VCCB through a pull-up resistor. If unused, connect directly to ground.
7 SCLB Input/Output Serial clock bus, B-side. Connect to VCCB through a pull-up resistor. If unused, connect directly to ground.
8 VCCB Supply B-side and device supply voltage (2.7 V to 5.5 V)
