DESCRIPTION
The
2N4856A/4857A/4858A
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 SOT-23 packages, see the
J/SST111 series data sheet. For
similar duals, see the
2N5564/5565/5566 data sheet.
