RFIN, RFOUT
This pin is DC coupled and matched to 50 Ohm. Blocking capaci-
tors are required if RF line potential is not equal to 0V.
4, 5, 6, 7, 8, 9
V6 - V1
See truth table and control voltage table.

N/C
This pin should be connected to PCB RF ground to maximize
performance

VEE
Supply Voltage -5V ± 10%
Suggested Driver Circuit (One Circuit Required Per Bit Control Input)
9 - 96
Simple driver using inexpensive standard logic ICs provides fast
switching using minimum DC current.
* Recommended value to suppress unwanted RF signals at V1 -
V6 control lines.
