General Description
The G3402 is a qual bidirectional I2C and SMBUS voltage-level translator with an output enable (OE) input, and is operational from 1.2V to 3.3V VCCA and 2.5V to 5.5V VCCB. It allows bidirectional voltage translations between 1.2V and 5V, without use of directional pin. The low ON-state resistance (rON) of the switch ensures the connections to be with minimal propagati...
