Description
The HA4201 is a very wide bandwidth 1x1 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, 1mW Disabled), excellent differential gain and phase, and very high off isolation. When disabled, the output is switched to a high impedance state, making the HA4201 ideal for routing matrix equipment.
The HA4201 requires no external current source, and features fast switching and symmetric slew rates. The tally output is an open collector PNP transistor to VCC, and is activated whenever EN = 1 to provide an indication of crosspoint selection.
For applications which don't require a TALLY output, please refer to the HA4600 data sheet.
Applications
