MAX4359/MAX4360/MAX4456 19-1389 Rev 2 2/07 Low-Cost 4x4, 8x4, 8x8 Video Crosspoint Switches General Description Features The MAX4359/MAX4360/MAX4456 low-cost video cross- Eight (MAX4456) or Four (MAX4359/MAX4360) point switches are designed to reduce component count, Internal Buffers 250V/s Slew Rate board space, design time, and system cost. Each con- Three-State Output Capability tains a matrix of T-switches that connect any of their four Power-Saving Disable Feature (MAX4359) or eight (MAX4360/MAX4456) video inputs to 65MHz -3dB Bandwidth any of their buffered outputs, in any combination. Each Routes Any Input Channel to Any Output Channel matrix output is buffered by an internal, high-speed (250V/s), unity-gain amplifier that is capable of driving Serial or Parallel Digital Interface 400 and 20pF at 2.6V . For applications requiring P-P Expandable for Larger Switch Matrices increased drive capability, buffer the MAX4359/ 80dB All-Channel Off-Isolation at 5MHz MAX4360/MAX4456 outputs with the MAX4395 quad, 70dB Single-Channel Crosstalk operational amplifier. Straight-Through Pinouts Simplify Layout The MAX4456 has a digitally controlled 8x8 switch matrix Low-Cost Pin-Compatible Alternative to and is a low-cost pin-for-pin compatible alternative to the MAX456 (MAX4456) 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. Ordering Information Three-state output capability and internal, programmable PIN- PKG PART TEMP RANGE active loads make it feasible to parallel multiple devices PACKAGE CODE to form larger switch arrays. The inputs and outputs are 36 SSOP MAX4359EAX -40C to +85C A36-2 on opposite sides, and a quiet power supply or digital 24 SO MAX4359EWG -40C to +85C W24-2 input line separates each channel, which reduces crosstalk to -70dB at 5MHz.
