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.
