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/µs), unity-gain-stable buffers capable of driving 400 Ω 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 Ωloads.
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.
