PCA9306DCUR

Транслятор уровня напряжения, 2 входа, 64мА, 1.5нс, 0В до 5В, VSSOP-8.

The PCA9306DCUR is a 2-bit bidirectional I?C Bus and SMBus Voltage-level Shifter with an enable (EN) input and is operational from 1.2 to 3.3V VREF1 and 1.8 to 5.5V VREF2. The PCA9306 device allows bidirectional voltage translations between 1.2 and 5V, 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 addition to voltage translation, the PCA9306 device can be used to isolate a 400kHz bus from a 100kHz busby controlling the EN pin and disconnecting the slower bus during fast-mode communication.
