Texas Instruments PCA9306 Dual Bi-Directional I2C-Bus and SMBus Voltage Level-Translator PCA9306DCTTE4

The PCA9306 is a dual bi-directional voltage-level translator designed for I2C and SMBus applications. It supports voltage translation between various levels, including 1.2 V to 5 V, without the need for a direction pin. The device features a maximum propagation delay of less than 1.5 ns, making it suitable for standard-mode and fast-mode I2C devices. It operates with VREF1 ranging from 1.2 V to 3.3 V and VREF2 from 1.8 V to 5.5 V, allowing flexibility in mixed-voltage environments. The PCA9306 has low ON-state resistance of 3.5 Ω, which minimizes signal distortion, and provides high-impedance states when the enable (EN) pin is low. It is also designed to be 5-V tolerant on its I2C I/O ports, ensuring compatibility with various devices. The part is suitable for applications in servers, routers, personal computers, and industrial automation. Additionally, it offers robust ESD protection and latch-up performance, making it reliable for demanding environments. The PCA9306 is available in multiple package options, including SSOP, VSSOP, X2SON, and DSBGA.
