8.1 Application Information

The SN74AXC2T45 device can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. The SN74AXC2T45 device is ideal for use in applications where a push-pull driver is connected to the data I/Os. The maximum data rate can be up to 380Mbps when device translates a signal from 1.8V to 3.3V.

Figure 8-1 shows one example application where the SN74AXC2T45 device is used to translate low voltage error signals from a CPU to a higher voltage signal to properly drive the inputs of a system controller, thus alerting the system of any CPU errors such as overheating or other catastrophic processor errors.
