Description
The MAX4359/MAX4360/MAX4456 low-cost video crosspoint
switches are designed to reduce component count,
board space, design time, and system cost. Each contains
a matrix of T-switches that connect any of their four
(MAX4359) or eight (MAX4360/MAX4456) video inputs to
any of their buffered outputs, in any combination. Each
matrix output is buffered by an internal, high-speed
(250V/µs), unity-gain amplifier that is capable of driving
400Ω and 20pF at 2.6VP-P. For applications requiring increased drive capability, buffer the MAX4359/MAX4360/MAX4456 outputs with the MAX4395 quad, operational amplifier.
The MAX4456 has a digitally controlled 8x8 switch matrix
and is a low-cost pin-for-pin compatible alternative to the
popular MAX456. The MAX4359/MAX4360 are similar to
the MAX4456, with the 8x8 switch matrix replaced by a
4x4 (MAX4359) or an 8x4 (MAX4360) switch matrix.
Three-state output capability and internal, programmable
active loads make it feasible to parallel multiple devices
to form larger switch arrays. The inputs and outputs are
on opposite sides, and a quiet power supply or digital
input line separates each channel, which reduces
crosstalk to -70dB at 5MHz. For applications demanding
better DC specifications, see the MAX456 8x8 video
crosspoint switch.
