DESCRIPTION
The J/SST111 series consists of all-purpose analog switches
designed to support a wide range of applications. The
J/SST113 are useful in a high-gain amplifier mode.
The J series, TO-226AA (TO-92) plastic package, provides
low cost, while the SST series, TO236 (SOT-23) package,
provides surface-mount capability. Both the J and SST series
are available in tape-and-reel for automated assembly (see
Packaging Information).
For similar products in TO-206AA(TO-18) packaging, see the
2N/PN/SST4391 series, 2N4856A/4857A/4858A, and
2N5564/5565/5566 (duals) data sheets.
