Each RF path can be closed by applying ground (TTL "High" for
Option T24) to the corresponding "drive" pin. In general, all other
RF paths are simultaneously opened by internal logic. See
for drive connection diagrams.

The default operation of the switches is break- before- make.
Make- before- break switching can be accomplished by
simultaneously selecting the "drive" pins for old RF path and new
RF path. Once the new RF path is closed (15 ms), de- select the
old RF path "drive" pin while leaving the new RF path "drive" pin
selected. The switch circuitry will automatically open the old RF
path while leaving the new RF path engaged.
