8x4 Video Crosspoint Switches with Buffers
_______________General Description
The MAX458/MAX459 are crosspoint switches with eight
input channels and four high-speed, buffered output
channels. The MAX458 output buffer is configured with a
gain of one, while the MAX459 buffer has a gain of two. In
each device, any one of eight input lines can be connect-
ed to any of four output amplifiers. The output buffers are
capable of driving loads of 75Ω.
Data interface can be accomplished by either a 16-bit
serial or a 6-bit parallel connection. In the serial mode,
the MAX458/MAX459 are SPI
TM
, QSPI
TM
, and Microwire
TM
compatible. In parallel mode, the MAX458/MAX459 are
compatible with most microprocessor buses. Three-state
amplifier output capability makes it possible to multiplex
MAX458/MAX459s to form larger switch networks. The
output buffers can be disabled individually or the entire
device can be shut down to conserve power.

Note 1:
Outputs may be shorted to any supply pin or ground as long as package power dissipation ratings are not exceeded.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 5:
All logic levels are guaranteed over the range of V
S
= ±4.75V to ±5.25V.
Note 6:
Differential phase and gain measured with a 40 IRE (285.7mV), 3.58MHz sine wave superimposed on a linear ramp of 0 IRE
to 100 IRE (714.3mV). “The IRE scale is a linear scale for measuring, in arbitrary IRE units, the relative amplitudes of the var-
ious components of a television signal” (from the “Television Engineering Handbook”, edited by K. Blair Benson, McGraw
Hill). This system defines 100 IRE as reference white, 0 IRE as the blanking level, and -40 IRE as the sync peak. The equip-
ment used for the test signal generated 714.3mV (100 IRE) as reference white and -285.7mV (-40 IRE) as sync. The modu-
lation used was 285.7mV (40 IRE), which conforms to the EIA color signal standards.
Note 7:
For MAX458, step input from +2V to 0V; for MAX459, step input from +1V to 0V. All unused channels grounded and all
unused amplifiers disabled.
Note 8:
Test input channel programmed to an output and grounded through a 75Ω resistor. Adjacent input is programmed to an
adjacent output and driven by a 10MHz, 4Vp-p sine wave.
Note 9:
Same as Note 6 above, except driven input and output are not adjacent to test input/output.
Note 10:
All inputs but the test input are driven by a 10MHz 4Vp-p sine wave. All outputs except the test output are connected to driven inputs.
Note 11:
Same as Note 9 above, except with test channel programmed off.
