Key Features

4-channel (4 SCL/SDA pairs), bidirectional buffer isolates capacitance and allows 400 pF on port B of the device.
Voltage level translation from port A (1 V to VCC(B)  1.5 V) to port B (3.0 V to 5.5 V).
Requires no external pull-up resistors on lower voltage port A.
Active HIGH repeater enable input.
Open-drain inputs/outputs.
Lock-up free operation.
Supports arbitration and clock stretching across the repeater.
Accommodates Standard-mode and Fast-mode I.
