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.

For a 4 x 1 crosspoint without Tally outputs or with synchro­nous control signals, please refer to the HA4314B and
HA4344B Data Sheets, respectively.

PC Board Layout

The frequency response of this circuit depends greatly on
the care taken in designing the PC board. The use of low

inductance components such as chip resistors and chip
capacitors is strongly recommended, while a solid
ground plane is a must!

Attention should be given to decoupling the power supplies.
A large value (10µF) tantalum in parallel with a small value
(0.1µF) chip capacitor works well in most cases.

Keep input and output traces as short as possible, because
trace inductance and capacitance can easily become the
performance limiting items.
