Description and Introduction
8-bit I2C-bus and SMBus I/O port with interrupt, 2-kbit EEPROM and 6 address pins The **PCA9501D** from NXP Semiconductors is a versatile I²C bus repeater designed to extend the range and reliability of I²C communication systems. This bidirectional voltage-level translator and repeater supports both Standard-mode (up to 100 kHz) and Fast-mode (up to 400 kHz) I²C bus speeds, making it ideal for applications requiring signal integrity across different voltage domains.  
Featuring a built-in voltage-level translation function, the PCA9501D seamlessly bridges I²C buses operating at different voltages (ranging from 2.3V to 5.5V), eliminating the need for additional level-shifting components. Its robust design includes hysteresis on all inputs to enhance noise immunity, ensuring stable performance in electrically noisy environments.   The device also incorporates a one-shot circuitry that prevents bus lock-ups by limiting low-to-high transition times, further improving system reliability. With its compact SO8 package, the PCA9501D is well-suited for space-constrained designs in industrial, automotive, and consumer electronics applications.   Key features include low standby current consumption, compatibility with I²C and SMBus protocols, and hot-swap capability, making it a practical solution for extending I²C networks while maintaining signal integrity. The PCA9501D is a reliable choice for designers seeking to enhance the performance and flexibility of their I²C-based systems. |
