FEATURES
DESCRIPTION
•
•
•
The LMH™ family of products is joined by the
LMH6584 and the LMH6585 high speed, nonblocking,
analog,
crosspoint
switches.
The
LMH6584/LMH6585 are designed for high speed, DC
coupled, analog signals such as high resolution video
(UXGA and higher). The LMH6584/LMH6585 have 32
inputs and 16 outputs. The non-blocking architecture
allows an output to be connected to any input,
including an input that is already selected. With fully
buffered inputs the LMH6584/LMH6585 can be
impedance matched to nearly any source impedance.
The buffered outputs of the LMH6584/LMH6585 can
drive up to two back terminated video loads (75Ω
load). The outputs and inputs also feature high
impedance inactive states allowing high performance
input and output expansion for array sizes such as 32
x 32 or 64 x 16 by combining two devices. The
LMH6584/LMH6585 are controlled with a 4 pin serial
interface. Both single serial mode and addressed
chain modes are available.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications, see the Electrical
Characteristics tables.
The maximum power dissipation is a function of TJ(MAX)and θJA. The maximum allowable power dissipation at any ambient temperature
is PD = (TJ(MAX) – TA)/ θJA. All numbers apply for packages soldered directly onto a PC Board.

Electrical Table values apply only for factory testing conditions at the temperature indicated. No specification of parametric performance
is indicated in the electrical tables under conditions different than those tested.
Room Temperature limits are 100% production tested at 25°C. Device self heating results in TJ ≥ TA, however, test time is insufficient for
TJto reach steady state conditions. Limits over the operating temperature range are ensured through correlation using Statistical Quality
Control (SQC) methods.
Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
The channel bandwidth varies over the different channel combinations and with expansion. See the application section for more details.
Slew Rate is the average of the rising and falling edges.
Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
Negative input current implies current flowing out of the device.
