The 74FCT162244CTPVCT is a 16-bit non-inverting buffer with 3-state outputs from the 74FCT series, designed for 5 V logic systems. It packs four 4-bit elements into a single 48-SSOP package, each element sourcing or sinking 24 mA — enough to drive a heavily loaded backplane or memory bus without external line drivers.
The 24 mA output drive (both high and low) is the headline number for this part. In a 5 V system, 24 mA can charge a 50 pF bus capacitance in roughly 2 ns, which keeps signal edges clean on a 16-bit parallel bus running at 50 MHz to 100 MHz. If your trace length or fan-out pushes the load beyond 24 mA per line, you will need a stronger buffer or a transceiver with higher drive — the 74FCT162244CTPVCT is not that part. The symmetric drive also simplifies timing analysis: rise and fall times match closely, reducing skew between bits.
Package and footprint — 48-BSSOP (7.50 mm wide)
The 48-BSSOP body is 7.50 mm wide with a 0.635 mm pitch — a fine-pitch SSOP that demands a controlled reflow profile and careful stencil design. This is a surface-mount-only part; no through-hole variant exists.
The ROHS3 rating covers the full ten restricted substances, including the four phthalates, so it passes European and California regulatory requirements for lead-free manufacturing. No successor or second-source part is listed in the official record, but the 74FCT series is a mature logic family with multiple suppliers; cross-referencing to a TI or NXP equivalent is straightforward if dual-sourcing becomes a priority.
Because the lifecycle is active, there is no premium for last-time-buy inventory — the supply chain is stable, and lead times are typical for a mature logic IC in a 48-SSOP package. Submit an RFQ for a firm price and delivery commitment tailored to your BOM line.
