• RF Switching and Routing
The HA4404B is a very wide bandwidth 4 x 1 crosspoint
switch ideal for professional video switching, HDTV, com-
puter monitor routing, and other high performance applica-
tions. The circuit features very low power dissipation
(105mW Enabled, 4mW Disabled), excellent differential gain
and phase, and very high off isolation. When disabled, the
output is switched to a high impedance state, making the
HA4404B ideal for routing matrix equipment.
The HA4404B requires no external current source, and fea-
tures fast switching and symmetric slew rates. The tally out-
puts are open collector PNP transistors to V+ to provide an
indication of crosspoint selection.
For a 4 x 1 crosspoint without Tally outputs or with synchro-
nous control signals, please refer to the HA4314B and
HA4344B Data Sheets, respectively.
