PDF datasheet for the TI SN74LVT162245DLR, a 16-bit 3.3 V bus transceiver from the LVT family. The 162 prefix marks the versions with built-in series damping resistors on the outputs. The DL suffix denotes an SSOP package, and R means tape-and-reel supply. At 39.1 KB it is a fairly short document. Use it to map the two direction and enable pin pairs when you trace wide data buses. Do not swap in a plain 16245 without checking, because the series resistors change how the outputs drive the line.
