TCA39306DCUR
ActiveFM+ I²C BUS AND SMBUS VOLTAGE TRANSLATOR
Description
General part information
TCA39306 Series
The TCA39306-Q1 is a dual bidirectional voltage-level translator compatible with I 2C, SMBus, and I 3C with an enable (EN) input, and is operational from 0.9-V to 3.3-V V REF1 and 1.8-V to 5.5-V V REF2.
The device allows bidirectional voltage translations between 0.85 V and 5 V, without the use of a direction pin. The low ON-state resistance (R ON) of the switch allows connections to be made with minimal propagation delay. When EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports. When EN is low, the translator switch is off, and a high-impedance state exists between ports.
In addition to voltage translation, the TCA39306-Q1 can be used to isolate a higher speed bus from a lower speed bus by controlling the EN pin to disconnect the slower bus during fast-mode communication.
