Operating between 1.2 and 3.3V VREF1 and 1.8 and 5.5V VREF2, the PCA9306DCTR is a dual bidirectional I²C and SMBus voltage-level Translator IC with an enable (EN) input. This article will introduce its features, applications and datasheet.
PCA9306DCTR Description
Operating between 1.2 and 3.3V VREF1 and 1.8 and 5.5V VREF2, the PCA9306DCTR is a dual bidirectional I²C and SMBus voltage-level Translator IC with an enable (EN) input. Without a direction pin, it enables bidirectional voltage translations between 1.2 and 5V. Minimal propagation delay is possible when making connections thanks to the switch's low ON-state resistance (RON). Bidirectional data flow across ports is possible when EN is high because the translator switch is turned on and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively. The translator switch is off and there is a high-impedance state between the ports when EN is low.
