This chip has failed on a board here, and I've temporarily swapped in a good one from another board. But now I need to replace that one. Package is TSSOP8.

What is it?

The bar across one end suggests "diode array", and the "33" might stand for "3.3V", which makes sense in this context.

EDIT: Oh, I think I found it.

SN74LVC2T45DCTR
"2-Bit Dual Supply Transceiver with Configurable Voltage-Level Shifting and 3-State Outputs"
