74FCT buffer for 5V bus isolation and fan-out
The Cypress CY74FCT162244CTPVC is a 16-bit buffer in the 74FCT series — a fast CMOS logic family that balances propagation delay with lower power than bipolar 74F or 74ABT. Organized as four independent 4-bit elements with non-inverting outputs and 3-state control, it fits designs needing a clean 5V bus isolation stage, clock distribution fan-out, or memory address buffering on a 48-SSOP footprint. The supply range is 4.5V to 5.5V, so it lives on a 5V rail only — not a 3.3V or mixed-voltage backplane. The industrial temperature grade (-40°C to 85°C) suits factory automation, outdoor telecom cabinets, and motor-drive control boards where the ambient stays inside that window.
Each output can source or sink 24 mA, symmetrical. That's enough to drive a bank of CMOS inputs on a short PCB trace, or a handful of LED indicators through series resistors, but not a 50-ohm backplane or a long ribbon cable. If you need more current per pin, the 74ABT or 74BCT families push 32 mA or 48 mA — but this part's drive is fine for local fan-out within a card. The 3-state outputs let you share the bus with other drivers; just mind the turn-on/turn-off timing if multiple buffers fight for the same line.
Package and footprint — 48-SSOP
The 48-BSSOP body (0.295 inch wide, 7.50 mm) is a common fine-pitch SSOP footprint.
Lifecycle and compliance — still a current-production part
The 74FCT series is mature but still supported — expect long lead times typical of a legacy logic family, not a fast-moving commodity.
