Description
The ISL83072EIBZA is a 3.3V, dual-channel, bidirectional I²C bus buffer from Renesas. It enhances signal integrity in I²C and SMBus systems by buffering data (SDA) and clock (SCL) lines, supporting up to 400kHz (Fast-mode).
Key features:
- Voltage translation: Compatible with 2.5V to 5.5V buses.
- Low standby current: <1µA (typical) for power efficiency.
- High noise immunity: Built-in hysteresis and noise filters.
- Hot-swap capable: Prevents bus lock-up during live insertion.
Applications include servers, industrial systems, and consumer electronics where I²C signal isolation or level shifting is needed. The 8-lead SOIC package ensures compact PCB integration.
For more details, refer to the datasheet.
