♦ Routes Any Input Channel to Any Output Channel

♦ Switches Standard Video Signals

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 400Ω and 20pF to ±1.3V. For appli-

c a tions re q uiring inc re a s e d d rive c a p a b ility, the

MAX456 outp uts c a n b e c onne c te d d ire c tly to two

MAX470 quad, gain-of-two video buffers, which are

capable of driving 75Ω loads.

♦ Serial or Parallel Digital Interface

♦ Expandable for Larger Switch Matrices

♦ 80dB All-Channel Off Isolation at 5MHz

♦ 8 Internal Buffers with:

250V/µs Slew Rate, Three-State Output Capability,

Power-Saving Disable Feature, 35MHz Bandwidth

Three-state output capability and internal, programma-

ble active loads make it feasible to parallel multiple

MAX456s and form larger switch matrices.

Dice*

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.

Ordering Information continued on last page.

* Dice are specified at T_A= +25°C, DC parameters only.
