Questions
Is there a KiCad symbol and footprint for the SN75185DB?
Yes. The symbol is EasyEDA_Cloud:SN75185DWG4 and the footprint Package_SO:SSOP-20_5.3x7.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN75185DB?
SSOP-20-208mil, with 20 pins. Its footprint is drawn on this page.
Where is the SN75185DB datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN75185DB?
JLCPCB lists it as part C544642, with 3 in stock; the sellers' links on this page open their listings.
What can replace the SN75185DB?
Parts like it in the library: the MAX3223EAP+T by Maxim Integrated (Analog Devices), the SP3222EEA-L/TR by MaxLinear, the WS3222ECA by NJGW and the MAX3223EEAP+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
