DESCRIPTION
The J/SST174 series consists of p-channel analog switches
designed to provide low on-resistance and fast switching. This
series simplifies series-shunt switching applications when
combined with the Siliconix J/SST111 series.
The TO-226AA (TO-92) plastic package provides a low-cost
option, while the TO-236 (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).
