The SST177 is a single P-Channel JFET switch

SST177

P-CHANNEL JFET

Linear Systems replaces discontinued Siliconix SST177

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 SST177 simplifies series-shunt

switching applications

.

The hermetically sealed TO-72 package is well suited

for military applications. The TO-92 package provides a

lower cost commercial option

SST177 Applications:



Analog Switches



Choppers



Sample-and-Hold



Normally “On” Switches



Current Limiters

SST177 Benefits:



Low Error Voltage



High-Speed Analog Circuit Performance



Negligible “Off-Error,” Excellent Accuracy



Good Frequency Response



Eliminates Additional Buffering
