SCES878 March 2019 SN74AXCH4T245
The SN74AXCH4T245 device can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. The SN74AXCH4T245 device is ideal for use in applications where a push-pull driver is connected to the data I/Os. The max data rate can be up to 380 Mbps when device translates a signal from 1.8 V to 3.3 V.
One example application is shown in Figure 11, where the SN74AXCH4T245 device is used to translate a low voltage UART signal from an SoC to a higher voltage signal which properly drive the inputs of the bluetooth module, and vice versa.
