Data Sheet
HA4314B
January 1999 File Number 3679.7
400MHz, 4 x 1 Video Crosspoint Switch
The HA4314B 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
HA4314B ideal for routing matrix equipment.
The HA4314B requires no external current source, and
features fast switching and symmetric slew rates.
For a 4 x 1 crosspoint with Tally outputs (channel indicators)
or with synchronous control signals, please refer to the
HA4404B and HA4344B data sheets, respectively.
For audio channels requiring larger signal swings, please
refer to the CD74HC22106 (8 x 8), CD22M3493 (12 x 8),
and CD22M3494 (16 x 8) data sheets.
