DESCRIPTION
The U290/U291 are high-performance JFET analog switches
designed to offer low on-resistance and fast switching. This
series features the lowest on-resistance of any JFET in the
industry today.
TheTO-206AC (TO-52) hermetically sealed case makes this
series suitable for military applications.
