HA4344B
350MHz, 4x1 Video Crosspoint Switch
with Synchronous Controls
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.
