Hey Keisuke,
I don't believe they are using the right prefix for these orderables. They need to begin with "SN54".
Hi Dylan,
Thank you for your advice. I'll confirm with my customer.
Best regards,
Keisuke
Hi Dylan,
Sorry for bother you.
I cannot find it on your web site, are these EOL products?
SN7474J ⇒ SN5474J
SN74175J ⇒ SN54175J
Best regards,
Keisuke
Decades ago, most TTL devices were replaced by LS-TTL devices (because they have mostly the same characteristics, but much lower power dissipation).
SN5474 and SN54175 are indeed no longer produced. It should be possible to simply replace them with SN54LS74AJ and SN54LS175J, but I do not know what qualification requirements your customer has.
Hi Clement san,
Noted with thank you. I will promote SN54LS74AJ and SN54LS175J.
Best regards,
Keisuke
