The TPT29306 device is a dual bidirectional I2C andSMBus voltage-level translator with an enable (EN) input,and work from 1.2V to 3.6V VREF1 and 1.8V to 5.5V VREF2.The 3.5Ω Ron make the minimal propagation delay <1.5ns.If EN is high, the translator switch is ON, and the SCL1and SDA1 I/O are connected to the SCL2 and SDA2 I/O,will allow bidirectional data flow between ports. If EN islow, the translator switch is off, and a high-impedancestate exists between ports to isolate both sides.The TPT29306 can also be used to run two buses, one is400 kHz and the other is 100 kHz. If the two buses areoperating at different frequency, the 100 kHz bus must beisolated when the other 400 kHz bus is required. If themaster is running at 400 kHz, the maximum systemfrequency may be less than 400 kHz because of thedelays added by the translator.As with the standard I2C-bus system, pull-up resistors arerequired in both sides, to provide the logic HIGH levels onthe translator’s bus. The device is designed to work withSM, FM and FM+ I2C-bus devices in addition to SMBusdevices. The maximum frequency is dependent on theRC time constant, but generally supports > 2 MHz.TPT29306 is available in MSOP8, VSSOP8, DFN1.4X1-8L and DFN3X4-8L(none e-pad) package, and ischaracterized from –40°C to +85°C.
