PCA9306DQER

The PCA9306DQER is a 2-bit bidirectional I²C Bus and SMBus Voltage-level Shifter with an enable input. The PCA9306 allows bidirectional voltage translations between 1.2 and 5V without the use of a direction pin. The low ON-state resistance 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.

• I²C and SMBus compatible
• Provides bidirectional voltage translation with no direction pin
• Lock-up-free operation for isolation when EN = Low
• Flow through pinout for ease of printed-circuit board trace routing
• Latch-up performance exceeds 100mA per JESD 78
• ESD protection exceeds JESD 22
• Green product and no Sb/Br
