Questions
Is there a KiCad symbol and footprint for the SN75185N?
Yes. The symbol is EasyEDA_Cloud:SN75185DWG4 and the footprint Package_DIP:DIP-20_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN75185N?
PDIP-20, with 20 pins. Its footprint is drawn on this page.
Where is the SN75185N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN75185N?
JLCPCB lists it as part C1544836, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SN75185N?
Parts like it in the library: the AD230AN by Analog Devices, the AD230JN by Analog Devices, the AD233JN by Analog Devices and the ADM230LJN by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
