Description
The SD211DE/SST211 series consists of enhancement-
mode MOSFETs designed for high speed low-glitch
switching in audio, video, and high-frequency
applications. The SD211 may be used for 5-V analog
switching or as a high speed driver of the SD214. The
SD214 is normally used for 10-V analog switching.
These MOSFETs utilize lateral construction to achieve
low capacitance and ultra-fast switching speeds. An
integrated Zener diode provides ESD protection. These
devices feature a poly-silicon gate for manufacturing
reliability.
For similar products see: quad array—SD5000/5400
series and non-Zener protection—SD210DE/214DE.
