Datasheet for the Texas Instruments SN74S374N, an octal D-type edge-triggered flip-flop from the Schottky TTL family with three-state outputs. The N suffix denotes the plastic through-hole DIP package. At 16.0 KB the file is likely a condensed product sheet. When repairing vintage computer or arcade boards, use it to find the clock, output-enable and data pins so you can probe for a stuck bus line. Check that the replacement belongs to the same logic family, because speed and drive strength differ between S, LS and HC versions.
