The Texas Instruments CD74ACT541E is an octal (8-bit) non-inverting buffer with 3-state outputs from the 74ACT family. It provides 24 mA source and sink current per channel, enough to drive a standard TTL load or a short backplane trace. The 3-state outputs let you isolate the bus when the output-enable line is deasserted, which is the standard interface for shared data buses in microprocessor or memory systems.
CD74ACT541E is Active in production. No discontinuation or last-time-buy has been announced.
Yes, CD74ACT541E is ROHS3 compliant, meaning it meets the latest EU RoHS directive for lead-free and restricted-substance limits.
The SN74ACT541 is a functional equivalent from the same 74ACT family — same octal non-inverting buffer with 3-state outputs, same 24 mA drive, same 4.5 V to 5.5 V supply. The CD74 prefix indicates the original TI commercial-grade line; the SN prefix is the standard prefix. Both are through-hole 20-DIP parts and are pin-compatible. Verify the exact temperature grade and package marking on the SN variant before substituting.
