It's a straight-through line driver — data in on one side, data out on the other, with an output-enable that puts the bus into high-impedance when pulled high. ## Output drive — 32 mA source, 64 mA sink The 32 mA source and 64 mA sink per output is the headline loading spec. That's enough to drive a handful of TTL inputs or a short backplane trace without needing an external bus transceiver. If your load exceeds that per-pin limit, you'll need to parallel outputs or add a discrete buffer stage. ## Package and footprint — 20-SOIC wide The 20-SOIC package with a 7.50 mm body width is the wide-body variant — not the narrow 3.90 mm SOIC-20. The footprint is standard for wide SOIC-20, so any board already laid out for a 74FCT541 in that body will take this part with no layout change. Surface-mount only; no through-hole option on this code. ## Lifecycle and compliance — active, RoHS3 The ROHS3 compliance covers the full EU directive — no lead, no restricted substances in the bill.","metaTitle":"CY74FCT541TSOC 74FCT Buffer, Non-Inverting, 20-SOIC","metaDescription":"CY74FCT541TSOC 8-bit buffer with 3-state outputs, 32mA/64mA drive, -40°C to 85°C.
