48-SSOP footprint and rework profile
The 74FCT162244CTPVG8 comes in a 48-BSSOP package with 0.295-inch body width and 7.50 mm body width — the 0.025-inch (0.635 mm) pitch is wide enough for hand soldering with a fine chisel tip, no hot-air station required for removal if you have a good vacuum pickup tool. Pin 1 is clearly marked by the chamfered corner on the top mold and the silkscreen dot on the PCB footprint; the orientation is unambiguous even under a magnifying lamp. The 1.2 mm seated height leaves clearance under a conformal coat spray nozzle. Bulk packaging means the parts arrive in tubes or trays, not tape-and-reel — the leads are straight, not formed to a carrier pocket, so you don't have to reform them before placing on the solder paste. The SSOP lead frame is copper with a matte-tin finish; the solder joint wets well with SAC305 paste at a 210°C peak reflow profile. No moisture sensitivity level is stated in the record, so a standard 48-hour floor life at ≤30°C/60% RH is a safe assumption for hand assembly.
The 24 mA source and 24 mA sink capability at the outputs is enough to drive a 50 Ω terminated backplane trace or a bank of LED indicators through a 220 Ω series resistor without an external buffer. The 3-state outputs let multiple devices share a common data bus; the output enable control gates the bus access per element. Four elements of four bits each gives a 16-bit bus width — one package handles a full 16-bit data path. The non-inverting buffer topology preserves signal polarity, so it works as a straight line driver or a clock distribution fan-out where you need to regenerate a 5 V logic level without inversion.
Active production — no end-of-life notice
The 74FCT series is a mature 5 V logic family with ongoing manufacturing support; there is no announced last-time-buy date. For BOM planning, this part is safe to specify for new designs that require a 5 V 16-bit buffer in a 48-SSOP footprint. The Bulk package format means the parts are not on continuous tape-and-reel replenishment, so lead time may vary with the lot size requested.
