8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The LMH6574 is a high-speed 4:1 analog multiplexer, optimized for very high speed and low distortion. With

selectable gain and excellent AC performance, the LMH6574 is ideally suited for switching high resolution,

presentation grade video signals. The LMH6574 has no internal ground reference. Single or split supply

configurations are both possible. The LMH6574 features very high speed channel switching and disable times.

When disabled the LMH6574 output is high impedance making MUX expansion possible by combining multiple

devices. See Multiplexer Expansion.

8.1.1 Multiplexer Expansion

It is possible to use multiple LMH6574 devices to expand the number of inputs that can be selected for output.

Figure 31 shows an 8:1 MUX using two LMH6574 devices.
