GND
Vee
Package base must also be connected to RF ground
Supply Voltage -5V ± 10%
Suggested Driver Circuit (One Circuit Required Per Bit Control Input)
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.
