Product details

Active lifecycle — no LTB risk for new designs

The product status is Active, meaning the manufacturer continues to produce and support this order code.

Bulk packaging — what it means for your line

For a repair depot or low-volume production run, Bulk is straightforward to handle. If your pick-and-place line expects tape-and-reel, factor in a tube-to-reel transfer step or confirm the supplier can offer an alternate packaging option at quote time.

Frequently asked questions

Is SN54LS640 8416101RA a direct replacement for SN74LS640?

The SN54LS640 and SN74LS640 are functionally identical — same octal bus transceiver with inverted data path. The difference is temperature grade: the 54LS variant is rated for -55 to 125 °C (military), while the 74LS variant is typically 0 to 70 °C (commercial). If your application requires the wider temperature range, the 8416101RA is the correct choice; if not, the 74LS640 may be a lower-cost alternative.
