The HA4404B is a very wide bandwidth 4 x 1 crosspoint
switch ideal for professional video switching, HDTV,
computer monitor routing, and other high performance
applications. 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
features fast switching and symmetric slew rates. The tally
outputs are open collector PNP transistors to V+ to provide
an indication of crosspoint selection.
• Open Collector Tally Outputs
For a 4 x 1 crosspoint without Tally outputs or with
synchronous control signals, please refer to the HA4314B
and HA4344B Data Sheets, respectively.
