General DescriptionThe 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 toany of their buffered outputs, in any combination. Eachmatrix output is buffered by an internal, high-speed(250V/µs), unity-gain amplifier that is capable of driving400Ωand 20pF at 2.6VP-P. For applications requiringincreased drive capability, buffer the MAX4359/MAX4360/MAX4456 outputs with the MAX4395 quad,operational amplifier.The MAX4456 has a digitally controlled 8x8 switch matrixand is a low-cost pin-for-pin compatible alternative to thepopular MAX456. The MAX4359/MAX4360 are similar tothe MAX4456, with the 8x8 switch matrix replaced by a4x4 (MAX4359) or an 8x4 (MAX4360) switch matrix.Three-state output capability and internal, programmableactive loads make it feasible to parallel multiple devicesto form larger switch arrays. The inputs and outputs areon opposite sides, and a quiet power supply or digitalinput line separates each channel, which reducescrosstalk to -70dB at 5MHz. For applications demandingbetter DC specifications, see the MAX456 8x8 videocrosspoint switch.________________________ApplicationsFeatures♦Eight (MAX4456) or Four (MAX4359/MAX4360)Internal Buffers250V/µs Slew Rate Three-State Output Capability Power-Saving Disable Feature65MHz -3dB Bandwidth

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.
