Texas Instruments datasheet for the SN74ABT16244ADL, a 16-bit buffer and line driver with 3-state outputs in SSOP (DL) package, provided as a 38.7 KB PDF. It should contain the pinout, enable logic, electrical characteristics and propagation delays. On a faulty board it is used to map which buffer feeds which bus line, confirm the output enables are asserted and find a channel shorted to ground or supply. Compare package outline with the part fitted, since TSSOP versions use a different pitch.
