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 propagation delay.
When OE is high, the translator switch is ON, and the AN I/O are connected to the BN I/O, respectively, allowing bidirectional data flow between ports.
When OE is low, the translator switch is off, and a high-impedance exists between ports.
Pull-up resistors are included on input and output lines internally to provide the logic high levels on the translator’s bus.
The size of the pull-up resistors are 10kΩ, and is allowed to use lower pull-up resistor value to minimal 1kΩ by adding ext...
