Pinout

Pin Name Type Function
1 VCC(A) power_in Port A supply voltage, which the datasheet specifies as 1.1 V minimum and VCC(B) − 1.0 V maximum.
2 A1 bidirectional Port A (lower-voltage side) I/O that follows B1 when EN is HIGH and is disabled when EN is LOW.
3 A2 bidirectional Port A (lower-voltage side) I/O that follows B2 when EN is HIGH and is disabled when EN is LOW.
4 GND power_in Supply ground at 0 V, the reference for all supply and input limits.
5 EN input Active-HIGH repeater enable input, with VIH of 0.9×VCC(A) to VCC(B) and VIL of −0.5 V to 0.1×VCC(A).
6 B2 bidirectional Port B (SMBus/I2C-bus side) I/O paired with A2, with VOL of 0.2 V maximum at IOL = 6 mA.
7 B1 bidirectional Port B (SMBus/I2C-bus side) I/O paired with A1, with VOL of 0.2 V maximum at IOL = 6 mA.
8 VCC(B) power_in Port B supply voltage, which the datasheet specifies as 2.5 V to 5.5 V.
