Part Number: SN74ABT244A

Hi Team,

Currently we found an opportunity to replace Nexperia 74ABT244D with TI SN74ABT244A. Customer needs a comparison table before input it in BOM. Could you please help provide it? I didn't find it on Seismic.

Thanks a lot.

BRs,

Francis

    Hi Francis,

    These devices are drop in replacements with no major differences. They were designed according to the same specs. The only difference between them is very slight differences in the typical propagation delay, but they have the same minimum and maximum values.
