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.

Ordering Information

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.
