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.
