Is there a KiCad symbol and footprint for the HT7544S?
Yes. the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7544S?
SOT-23-3, with 5 pins. Its footprint is drawn on this page.
Where is the HT7544S datasheet?
TDSEMIC publishes it: the Datasheet link on this page opens it.
Where can I order the HT7544S?
JLCPCB lists it as part C22466414, with 3,780 in stock; the sellers' links on this page open their listings.
What can replace the HT7544S?
Parts like it in the library: the HE2021A44HMR by HEERMICR, the HT7144 by HX, the HT7544 by HX and the LR8341A-T44 by LR. Check their datasheets: a part that fits the footprint may still differ in its ratings.
