The PCA9617A is an I²C-bus buffer that supports I²C-bus fast-mode plus devices operating at 1.2 V to 3.3 V. This device provides level-shifting between low voltage and higher voltage I²C-bus signals. It allows easy parallel expansion of I²C-bus systems with one bus operating at 1.8 V and the other bus operating at a higher voltage, e.g., 3.3 V or 5 V. Functions: - Level-shifting between low voltage and higher voltage I²C-bus signals - Supports I²C-bus fast mode plus (up to 1 MHz) - Supports hot swapping - Enables longer bus length with minimal impact on data rate Applications: - Communication between I²C devices operating at different voltage levels - Parallel expansion of I²C-bus systems - Communication between low power microcontrollers and I/O devices Alternative Components: - Texas Instruments PCA9613 - NXP Semiconductors PCA9509 - Analog Devices ADUM1250 Embedded Modules: - PCA9617A development board - I²C to CAN bus module with PCA9617A - I²C bus extender module using PCA9617A Related Q&A: 1.
