TPT29617A Dual Channel Bidirectional I2C Bus Level Shift and Repeater

　　The TPT29617A device is a dual channel I2C level shift and repeater function with an enable (EN) input, and work from 0.8 V to 5.5 V VREF1 and 2.2 V to 5.5 V VREF2. The SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, will allow bidirectional data flow between ports. If EN is low, the translator switch is off, and a high-impedance state exists between ports to isolate both sides. Dual channel, bidirectional buffer isolates capacitance and allows 540 pF on either side of the device at 1 MHz and up to 4000 pF at lower speeds. TPT29617A is available in SOP8 and MSOP8 package, and is characterized from −40°C to +125°C.
