The CAXC4T774QBQBRQ1: Rated for 310 Mbps data rate, this part keeps up with SPI and UART buses in infotainment and body-control modules — the propagation delay through the bidirectional path stays under the bit period at that speed, so no timing margin is lost on the bus.
The SN74LXC2T45DTTR is a 2-bit bidirectional translator from the 74LXC series rated at 420 Mbps, but it is only 2 channels per circuit versus the CAXC4T774QBQBRQ1's 4 channels — the pinout and channel count differ, so a board spin is required for a direct swap.
