What this bus driver does on the board
The CD74FCT822AEN is a BUS DRIVER from Texas Instruments' FCT SERIES, designed to buffer and drive bus lines in processor and memory subsystems. It sits in the Microcontrollers & Processors (MCU / MPU / DSP) category, meaning it's the glue logic that keeps address or data buses clean between the processor and its peripherals.
Package and rework considerations
Supplied in Bulk packaging — loose tubes or trays, not tape-and-reel, so it's a manual-placement or low-volume pick-and-place job. Being a through-hole or DIP-style package (typical for FCT-series bus drivers), it reworks cleanly under a soldering iron or hot-air station — you can lift the part without lifting the pad if you preheat the board to 80 °C first.
