8.1 Application Information

The SN74LVC2T45-Q1 device can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. The maximum data rate can be up to 420Mbps when the device translates signal from 3.3V to 5V. It is recommended to tie all unused I/Os to GND. The device should not have any floating I/Os when changing translation direction.
