The SST174 is a single P-Channel JFET switch

SST174

P-CHANNEL JFET

Linear Systems replaces discontinued Siliconix SST174

This p-channel analog switch is designed to provide low

on-resistance and fast switching. When used in

combination with the complimentary J/SST111 n-

channel family, the SST174 simplifies series-shunt

switching applications

.

SST174 Applications:

Analog Switches

Choppers

Sample-and-Hold

Normally “On” Switches

Current Limiters

SST174 Benefits:

Low Error Voltage

High-Speed Analog Circuit Performance

Negligible “Off-Error,” Excellent Accuracy

Good Frequency Response

Eliminates Additional Buffering
