PCA9306-Q1 Overview
Description
This dual bidirectional I2C and SMBus voltage-level translator, with an enable (EN) input, is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2. The PCA9306-Q1 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.
Key Features
- 2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I2C applications
- Compatible with I2C and SMBus
- Less than 1.5-ns maximum propagation delay to accommodate standard-mode and fast-mode I2C devices and multiple controllers
- Provides bidirectional voltage translation with no direction pin
- Low 3.5-Ω ON-state connection 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
- Lock-up-free operation for isolation when EN = Low
- Flow-through pinout for ease of printed-circuit board trace routing
- Latch-up performance exceeds 100 mA Per JESD 78, Class II
