HA456
FN4153.5
120MHz, Low Power, 8x8 Video
Crosspoint Switch
The HA456 is the first 8 x 8 video crosspoint switch suitable
for high performance video systems. Its high level of
integration significantly reduces component count, board
space, and cost. The crosspoint switch contains a digitally
controlled matrix of 64 fully buffered switches that connect
eight video input signals to any, or all, matrix outputs. Each
matrix output connects to an internal, high-speed (200V/μs),
unity gain buffer capable of driving 400Ω and 5pF to ±2V.
For applications requiring gain or increased drive capability,
the HA456 outputs can be connected directly to two
HFA1412 quad, gain of two video buffers, which are capable
of driving 75Ω loads.
This crosspoint’s true high impedance three-state output
capability, makes it feasible to parallel multiple HA456s and
form larger switch matrices.

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.
