Looks like Siliconix makes (made?) a cross for
the TL182. Here's the pinout
The TL182 is a dual SPST JFET switch
S1 1 14 S2
D1 2 13 D2 <-- the switch
3 12
4 11
I1 5 10 <-- ttl switch in
V+ 6 9 V-
5v 7 8 GND
Siliconix DG180/181/182's should work. The various
parts have 10,30, and 75 ohms of ON resistance.
