DESCRIPTION/ORDERING INFORMATION 

This dual bidirectional I 2C and SMBus voltage-level translator, with an enable (EN) input, is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2. 

The PCA9306DQER allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin. The low ON-state resistance (ron) 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 I 2C applications, the bus capacitance limit of 400 pF restricts the number of devices and bus length. Using the PCA9306DQER enables the system designer to isolate two halves of a bus; thus, more I 2C devices or longer trace length can be accommodated.
