The 2N4856JAN/JANTX/JANTXV all-purpose JFET analog
switches offer low on-resistance, low capacitance, good
isolation, and fast switching.
Hermetically-sealed TO-206AA (TO-18) packaging allows full
military processing (see Military Information). For similar
products in TO-226AA (TO-92) and TO-236 (SOT-23)
packages, see the J/SST111 series data sheet. For similar
duals, see the 2N5564/5565/5566 data sheet.
