This is circuit of DTL-TTL controlled buffered analog Switch. Due to its low lowleakage and 25ohm rOn, this circuit uses 2N4860 JFET. As a voltage buffer, this circuit uses LM 102. Here is the circuit :
A dual trace oscilloscope chopper can adapt this circuit. Adequate switch drive controlled DTL-TTL logic levels are generated by the DM7800 monolithic I.C. [Source: National Semiconductor Application Note]
