Questions
Is there a KiCad symbol and footprint for the SN75ALS191D?
Yes. The symbol is Analog & Interface:SN75ALS191 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN75ALS191D?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the SN75ALS191D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN75ALS191D?
JLCPCB lists it as part C2871261, with 4,451 in stock; the sellers' links on this page open their listings.
What can replace the SN75ALS191D?
Parts like it in the library: the SP3485EN-L/TR by MaxLinear, the SP485EEN-L/TR by MaxLinear, the SN75176BD by Texas Instruments and the MAX485ESA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
