With an enable (EN) input, the PCA9306 device is a dual bidirectional I 2C and SMBus voltage-level translator that operates between 1.2 and 3.3 V REF1 and 1.8 and 5.5 V REF2. This article will introduce its features, applications and datasheet.
PCA9306DCUR Description
With an enable (EN) input, the PCA9306 device is a dual bidirectional I 2C and SMBus voltage-level translator that operates between 1.2 and 3.3 V REF1 and 1.8 and 5.5 V REF2.
Without the need for a direction pin, the PCA9306 device facilitates bidirectional voltage translations between 1.2 V and 5 V. The switch's low ON-state resistance (R ON) enables connections to be made with the least amount of propagation delay. Bidirectional data flow between ports is enabled 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. The translator switch is off and there is a high-impedance state between the ports when EN is low.
PCA9306DCUR Features
Two bidirectional channels: It can translate voltage levels between 1.2 V and 5.5 V for both directions.
Enable pin: It can turn on or off the translation function by applying a high or low voltage to this pin.
Low on-state resistance: It has a resistance of 3.5 ohms when the translation function is on, which reduces signal distortion and power loss.
Fast propagation delay time: It has a delay time of 1.2 ns when the translation function is on, which allows high-speed data transfer.
Small package: It comes in a VSSOP-8 package, which has a size of 3 mm x 3 mm x 0.8 mm.
