Dual 4-bit inverting buffer with 3-state bus control
The NXP 74HCT240PW,112 is a dual 4-bit inverting buffer with 3-state outputs from the 74HCT logic family, packaged in a 20-TSSOP (4.40 mm width) for surface-mount assembly.
Package and board-fit for 20-TSSOP
The 20-TSSOP (0.173", 4.40 mm width) body with 0.65 mm pin pitch requires a standard TSSOP-20 footprint — the same land pattern used by the 74HCT240D,652 in SOIC-20, but with a narrower body width that saves board area. Surface-mount assembly with the Bulk package format means parts are tube-packed, not tape-and-reel — verify feeder compatibility if using automated pick-and-place for high-volume runs.
