4-bit parallel shift register — LS family logic
The Texas Instruments SN74LS395AD is a 4-bit parallel-in/parallel-out shift register from the LS logic family. It accepts parallel data on four inputs and shifts it through the register on each clock pulse, making it suited for data buffering, serial-to-parallel conversion, and temporary storage in TTL-level digital systems.
Package and sourcing posture
Supplied in a Bulk package format — loose tubes or trays rather than tape-and-reel, which suits low-volume prototyping, repair stock, or manual assembly lines where pick-and-place feeder setup is not justified.
