Bus transceiver for backplane buffering
The Texas Instruments SN74AS622DW is a bus transceiver — a bidirectional buffer designed to drive heavily loaded backplane or memory-bus lines. It sits between two data buses, translating signal levels and providing the fan-out needed to maintain signal integrity across multiple loads.
This is a current-production part, not a surplus-only item. The RoHS non-compliant flag means it uses leaded solder — still acceptable for military, aerospace, and industrial applications that have a RoHS exemption, and for legacy assembly lines that cannot transition to lead-free reflow.
Bulk delivery — plan for tube handling
The listed package is Bulk, which typically means the parts ship in tubes or trays rather than on tape-and-reel. If your pick-and-place line expects reeled components, factor in a tube-feeder changeover or a hand-load step for smaller runs. The actual device package is a standard SOIC wide-body (DW suffix) — the same footprint used across TI's 74AS and 74ACT logic families, so the board layout is interchangeable with other DW-package bus transceivers.
