HA456
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/
μ
s),
unity gain buffer capable of driving 400
Ω
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 75
Ω
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.
