Product details

5V bus buffer for industrial logic

The CY74FCT2541CTSOC: It is designed for driving heavily loaded backplane or memory bus lines where the 5V logic swing is required and the output can be disabled to share the bus with other drivers. The 15 mA source and 12 mA sink output drive is enough for a standard 5V TTL bus segment — enough to drive a few loads on a short backplane trace without external buffers. The 3-state control lets multiple devices talk on the same bus without contention.

Package and footprint — 20-SOIC wide-body

Packaged in a 20-SOIC wide-body (0.295", 7.50mm width) — the wider body compared to narrow SOIC (3.9mm) gives better thermal dissipation and easier hand-soldering for prototype work. If you need Tape & Reel for automated placement, check the suffix variant — this specific order code is Tube only.

Frequently asked questions

What is the difference between CY74FCT2541CTSOC and CY74FCT245CTSO?

The CY74FCT2541 is a non-inverting buffer, while the CY74FCT245 is a transceiver that can switch direction between A and B ports. Both are 8-bit, 3-state, same package and supply range. Choose the 2541 for unidirectional buffering and the 245 for bidirectional bus isolation.

Is CY74FCT2541CTSOC compatible with 3.3V logic levels?

No — the supply range is 4.75V to 5.25V, and the input thresholds are TTL/5V CMOS. Driving it from a 3.3V output will not reliably reach the VIH(min) level. For 3.3V buses, look at the 74LVTH or 74ABT families with 3.3V supply.
