Product details

8-bit buffer for 5V bus isolation

The CY74FCT2541TSOCT is an 8-bit non-inverting buffer with 3-state outputs from the 74FCT series, designed for 5V logic systems. It operates from a 4.75V to 5.25V supply and delivers 15mA source, 12mA sink per output — enough to drive standard TTL loads or a lightly loaded data bus.

Output drive and 3-state control

With 15mA output high and 12mA output low, this buffer can drive standard TTL loads. The 3-state outputs let you share a bus between multiple drivers.

Supply rail and temperature grade

The 4.75V to 5.25V supply range is a tight 5V ±5% window — this part expects a regulated 5V rail, not a loosely filtered one. If your board runs a 3.3V core with a separate 5V I/O rail, the buffer sits comfortably on that 5V side.

Lifecycle and sourcing posture

If you are dual-sourcing a 5V bus buffer, the 74FCT2541 footprint is common enough that a second-source qualification with a pin-compatible alternate is straightforward.

Frequently asked questions

What is the output current of CY74FCT2541TSOCT?

The buffer can source 15mA and sink 12mA per output, which is typical for a 5V 74FCT-series buffer driving standard TTL loads or a lightly loaded bus.

Does CY74FCT2541TSOCT have 3-state outputs?

Yes — the outputs are 3-state, allowing the buffer to be placed in high-impedance when the output enable is deasserted, which lets multiple devices share a common bus without contention.
