Description
The PCA9306USG from onsemi is a high-performance, dual-channel, bidirectional voltage-level translator specifically designed for I²C-bus and SMBus applications. It facilitates seamless communication between devices operating at different voltage domains without the need for a direction control pin. By utilizing a low 3.5Ω ON-state resistance, the translator ensures minimal signal distortion and maintains signal integrity across the interface.
Featuring a “flow-through” pinout, the device simplifies PCB trace routing, making it an excellent choice for compact board designs. With lock-up free operation and a wide supply voltage range (0V to 5.5V), the PCA9306USG provides a reliable and flexible solution for multi-voltage electronic systems where inter-device communication is critical.
