PCA9306
Description
The PCA9306 device is a dual bidirectional I2C and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2.
Key Features
- 1 2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I2C Applications
- Less than 1.5-ns Maximum Propagation Delay to Acmodate Standard-mode and Fast-mode I2C Devices and Multiple Masters
- Allows Voltage-level Translation Between
- Provides Bidirectional Voltage Translation with no Direction Pin
- Low 3.5-Ω ON-state Resistance Between Input and Output Ports Provides Less Signal Distortion
- 5-V Tolerant I2C I/O Ports to Support Mixed-mode Signal Operation
- High-impedance SCL1, SDA1, SCL2, and SDA2 pins for EN = Low
- Lockup-free Operation for Isolation when EN = Low
- Flow-through Pinout for Ease of Printed-circuitboard Trace Routing
- Latch-up Performance Exceeds 100 mA Per JESD 78, Class II
Applications
- I2C, SMBus, PMBus, MDIO, UART, low-speed SDIO, GPIO, and other two-signal interfaces
