FEATURES
DESCRIPTION
•
•
•
The LMH™ family of products is joined by the
LMH6580 and the LMH6581, high speed, nonblocking,
analog,
crosspoint
switches.
The
LMH6580/LMH6581 are designed for high speed, DC
coupled, analog signals such as high resolution video
(UXGA and higher). The LMH6580/LMH6581 each
has eight inputs and four outputs. The non-blocking
architecture allows any output to be connected to any
input, including an input that is already selected. With
fully buffered inputs the LMH6580/LMH6581 can be
impedance matched to nearly any source impedance.
The buffered outputs of the LMH6580/LMH6581 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 8
x 8 or 16 x 4 by combining two devices. The
LMH6580/LMH6581 are controlled with a 4 pin serial
interface that can be configured as a 3 wire interface.
Both serial mode and addressed modes are
available.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

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 ±3.3V Electrical
Characteristics and ±5V Electrical Characteristics.
If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

The maximum output current (IOUT) is determined by device power dissipation limitations. The maximum power dissipation is a function
of TJ(MAX), 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 ensured parametric performance is
indicated in the electrical tables under conditions different than those tested.
Room Temperature limits are 100% production tested at 25°C. Factory testing conditions result in very limited self-heating of the device
such that TJ = TA. Limits over the operating temperature range are specified 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 specified on shipped
production material.

This parameter is specified by design and/or characterization and is not tested in production.
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.
