Overview
The PCA9306DC1Z, produced by NXP USA Inc., is a dual bidirectional I2C-bus and SMBus voltage-level translator. This device is designed to facilitate bidirectional voltage translations between different voltage levels, ranging from 1.0 V to 5.5 V, without the need for a direction pin. It features an enable (EN) input that controls the translator switch, allowing for seamless communication between devices operating at different voltage levels. The PCA9306DC1Z is particularly useful in mixed-mode I2C-bus applications and supports Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus and SMBus protocols.
