Product details

40 ns access time — timing margin for 5V buses

The 63S281ANL: The 40 ns access time means the PROM can present valid data within 40 ns of the address being stable.

RoHS non-compliant — verify your assembly's exemption allowance for lead-bearing solder if the application requires it.

Supplied in Bulk (tubes or trays), not tape-and-reel. For pick-and-place lines, you will need to transfer to a feeder-compatible carrier or hand-place. The 20-PLCC J-Lead footprint matches standard PLCC-20 land patterns; the 9x9 mm body fits sockets as well as soldered joints. The 0°C to 75°C commercial range limits this part to indoor, temperature-controlled environments — not suitable for industrial or automotive under-hood use without additional thermal management.

Frequently asked questions

What is the access time of 63S281ANL?

The access time is 40 ns.

What is a replacement for 63S281ANL?

No direct replacement is listed in the official records. The 63S281ANL is a 1Kbit PROM; a functionally similar part with larger density is the 5962-8769002SA (4Kbit, 40 ns, parallel, military temp range), but verify pin compatibility and supply voltage (4.5V min vs 4.75V min) before substituting.
