• TTL Compatible Control Signals  
The HA4244 is a very wide bandwidth 1 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, excellent  
differential gain and phase, high off isolation, symmetric slew  
rates, fast switching, and a latched enable signal. When  
disabled, the output is switched to a high impedance state,  
making the HA4244 ideal for routing matrix equipment.  
The latched enable input allows for synchronized channel  
switching. When CLK is low the master control latch loads the  
next EN, while the closed slave control latch maintains the  
crosspoint in its current state. CLK switching high closes the  
master latch, loads the now open slave latch, and enables or  
disables the HA4244 according to the current state of the EN  
input.  
• Latched Enable Input for Synchronous Switching  
• Powers-Up in Disabled State; Avoids Bus Contention  
Applications  
• Professional Video Switching and Routing  
• Video Multiplexers  
This crosspoint’s design ensures that it powers up in the  
disabled state to eliminate bus contention concerns, and to  
minimize supply current draw at power up.  
• Computer Graphics  
• RF Switching and Routing  
• PCM Data Routing  
For applications requiring an asynchronous crosspoint  
switch, please refer to the HA4201 and HA4600 data sheets.
