_______________General Description
The MAX456 is the first monolithic CMOS 8 x 8 video
crosspoint switch that significantly reduces component
count, board space, and cost. The crosspoint switch
contains a digitally controlled matrix of 64 T-switches
that connect eight video input signals to any, or all, out-
put channels. Each matrix output connects to eight
internal, high-speed (250V/s), unity-gain-stable buffers
capable of driving 400
and 20pF to ±1.3V. For appli-
cations requiring increased drive capability, the
MAX456 outputs can be connected directly to two
MAX470 quad, gain-of-two video buffers, which are
capable of driving 75
loads.
Three-state output capability and internal, programma-
ble active loads make it feasible to parallel multiple
MAX456s and form larger switch matrices.
In the 40-pin DIP package, crosstalk (70dB at 5MHz) is
minimized, and board area and complexity are simpli-
fied by using a straight-through pinout. The analog
inputs and outputs are on opposite sides, and each
channel is separated by a power-supply line or quiet
digital logic line.
