Product details

Octal buffer for bus isolation and line driving

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.

Lifecycle and sourcing

The CD74ACT541E is listed as Active and ROHS3 compliant. No end-of-life or last-time-buy notice is in the record, so it remains a safe choice for new designs and production replenishment.

Frequently asked questions

Is CD74ACT541E obsolete or active?

CD74ACT541E is Active in production. No discontinuation or last-time-buy has been announced.

Is CD74ACT541E RoHS compliant?

Yes, CD74ACT541E is ROHS3 compliant, meaning it meets the latest EU RoHS directive for lead-free and restricted-substance limits.

Can CD74ACT541E be replaced by SN74ACT541?

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.
