The Texas Instruments SN74LVCR2245ADW is a single-element 8-bit non-inverting bus transceiver from the 74LVCR logic family, packaged in a 20-SOIC (7.50 mm wide body) for surface-mount assembly. It provides bidirectional level translation between two independent supply rails, with 3-state outputs on both the A and B ports to isolate the bus when the output-enable pins are deasserted.
It covers the common 1.8 V and 3.3 V rails without an external regulator, and the 1.65 V floor means it can work with a 1.8 V ±5 % supply and still have margin. If your design only needs 0°C to 70°C, there are cheaper commercial-grade parts in the 74LVC family, but the 125°C rating here is what you pay for when the environment demands it.
Output drive — 12 mA per pin, enough for a loaded bus
Each output is rated for 12 mA source and 12 mA sink. The 3-state outputs let multiple transceivers share the same bus lines.
