SN74LS244: part marking verification

Austin Schultz

Part Number: SN74LS244
Other Parts Discussed in Thread: SN54LS244

We are a partner with TI on end of life and obsolete inventory. We received part SN74LS244N back in 1999 (PN has 966 DC). Parts have no indication of the PN on them - only a dual marking: 66CJT0K on top line and 5616646-36929 on the bottom line. Lot number reference: LS244-9270.

Looking for confirmation that these part marking are indeed indicative of this orderable PN.

Please advise.

Thank you!

Hi Austin,

Could you send a picture of the part with marking visible?

Hi Austin,

I'm still looking into this issue but I can't tell and I don't know if we have any way to verify a marking from that far back.

It almost seems like it could be a military marking (which would lend itself to the SN54LS244) but I'm not sure. Has the customer tested any of these devices to find out?

Best,

Malcolm
