Another number for this one is a TL442CN if I recall correctly.
Dentron used the TI SN76514N / TL442CN on their SG-9 board, a 9 Mhz IF board / SSB Gen for transceivers.

3196 2009-06-17 09:32:55 Art Re: ic unobtanium Quest Components is showing 35 TL442CN available, although I am not
sure whether they have a minimum order or not.
They are reliable, I've ordered from them before. They are a
combination stocking distributor and parts broker, so they might not
actually be in their inventory.
I hope this works for you, with obsolete parts, vendors are generally
happy to sell them for any price-no holds are barred although
sometimes obsolete parts command very high prices-go figure::>
