The MAX4359/MAX4360/MAX4456 low-cost video cross-

point switches are designed to reduce component count,

board space, design time, and system cost. Each con-

tains 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 2.6V

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.
