HA4404B
July 1998
330MHz, 4 x 1 Video Crosspoint Switch with Tally Outputs
Description
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.
