Questions
Is there a KiCad symbol and footprint for the HT491EARZ?
Yes. the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT491EARZ?
SOP-14, with 14 pins. Its footprint is drawn on this page.
Where is the HT491EARZ datasheet?
HTCSEMI publishes it: the Datasheet link on this page opens it.
Where can I order the HT491EARZ?
JLCPCB lists it as part C50338896, with 268 in stock; the sellers' links on this page open their listings.
What can replace the HT491EARZ?
Parts like it in the library: the SP491EEN-L/TR by MaxLinear, the SP3070EEN-L/TR by MaxLinear, the GB491 by NJGW and the SIT3491EESD by SIT. Check their datasheets: a part that fits the footprint may still differ in its ratings.
