Questions
Is there a KiCad symbol and footprint for the 74HC540WS20ARBQ?
Yes. The symbol is 74xx:74LS540 and the footprint Package_SO:SOP-20_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 74HC540WS20ARBQ?
SOP-20-300mil, with 20 pins. Its footprint is drawn on this page.
Where is the 74HC540WS20ARBQ datasheet?
GR publishes it: the Datasheet link on this page opens it.
Where can I order the 74HC540WS20ARBQ?
JLCPCB lists it as part C47089304, with 326 in stock; the sellers' links on this page open their listings.
What can replace the 74HC540WS20ARBQ?
Parts like it in the library: the SN74HC245DTR(XBLW) by XBLW, the CJ74HC540AGN by Jiangsu Changjing Electronics Technology (CJ), the 74HC244D,653-JSM by JSMSEMI and the SN74HC240DTR(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
