NXP PCA9617AUK Dual Bidirectional I2C-Bus and SMBus Voltage-Level Translator

The NXP PCA9617AUK is a high-performance, dual bidirectional I2C-bus and SMBus voltage-level translator that is designed to provide seamless communication between devices operating at different voltage levels. This robust integrated circuit is an ideal solution for applications requiring the interfacing of peripherals or microcontrollers within multi-voltage systems.

Key Features

• Voltage Level Translation: Capable of translating between low voltage (down to 0.8V) and higher voltage (up to 5.5V) I2C-bus or SMBus signals, making it versatile for various applications.
• High-Speed Operation: Supports fast-mode plus (Fm+) I2C-bus speeds up to 1 MHz, ensuring swift data transfer rates for time-sensitive applications.
• Hot-Swappable: The PCA9617AUK can be added to or removed from a live backplane without turning the power off, ensuring minimal disruption to system operations.
• Enhanced Signal Integrity: Equipped with an integrated rise time accelerator for both the A-side and B-side, improving signal quality on heavily capacitive buses.
• Robust ESD Protection: Features 8 kV HBM (Human Body Model) ESD protection on all pins, safeguarding the device from electrostatic discharges during handling and operation.
• Fail-Safe Circuitry: The PCA9617AUK includes a fail-safe feature that ensures a logic high on SDA and SCL outputs when the inputs are unconnected.
• Power Supply Flexibility: Allows for separate supply voltages for both the A-side (VDD(A)) and the B-side (VDD(B)), accommodating a wide range of system configurations.

Applications

The PCA9617AUK is well-suited for a variety of applications that require voltage level translation for I2C-bus or SMBus signals. These include, but are not limited to:
