HA456
120MHz, Low Power, 8x8 Video
Crosspoint Switch
The HA456 is the first 8x8 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 8
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: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is 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.
