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 trans-
lations between 1.2V and 5V, without use of direc-
tional 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 be-
tween 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 trans-
lator’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 external resistor.
All channels have the same electrical characteristics,
and there is minimal deviation from one output to an-
other in voltage or propagation delay. This is a benefit
over discrete translation solutions, since the fabrica-
tion of the switch is symmetrical.
