• TTL Compatible Control Signals  
The HA4344B is a very wide bandwidth 4x1 crosspoint switch  
ideal for professional video switching, HDTV, computer  
display routing, and other high performance applications. This  
circuit features very low power dissipation, excellent  
differential gain and phase, high off isolation, symmetric slew  
rates, fast switching, and latched control signals. When  
disabled, the output is switched to a high impedance state,  
making the HA4344B ideal for matrix routers.  
The latched control signals allow for synchronized channel  
switching. When CK1 is low, the master control latch loads  
the next switching address (A0, A1, CS), while the closed  
(assuming CK2 is the inverse of CK1) slave control latch  
maintains the crosspoint in its current state. CK2 switching  
low closes the master latch (with previous assumption),  
loads the now open slave latch, and switches the crosspoint  
to the newly selected channel. Channel selection is  
asynchronous (changes with any control signal change) if  
both CK1 and CK2 are low.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free  
material sets; molding compounds/die attach materials and 100% matte  
tin plate termination finish, which are RoHS compliant and compatible  
with both SnPb and Pb-free soldering operations. Intersil Pb-free  
products are MSL classified at Pb-free peak reflow temperatures that  
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
