5V bus buffer for industrial backplanes
The CY74FCT2541TSOC is a single 8-bit non-inverting buffer with 3-state outputs from Cypress's 74FCT logic family. The 15mA source / 12mA sink drive handles moderate fan-out to multiple CMOS loads or a few TTL gates without external line drivers.
Lifecycle and BOM fit
No last-time-buy risk on the horizon. For dual-sourcing, the SN74ABT2245DW is a functional alternative — same 8-bit transceiver function in a 20-SOIC, 4.5V supply, 32mA drive, industrial temperature — but verify the direction control pinout difference (transceiver vs buffer) against your schematic.
