phase of better than 0.02% and 0.02° respectively, along with 0.1 dB flatness out to 60 MHz, make the AD8110/AD8111 ideal for video signal switching. The AD8110 and AD8111 include eight independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs so that off channels do not load the output bus. The AD8110 has a gain of +1, while the AD8111 offers a gain of +2. They operate on voltage supplies of ± 5 V w h i l e consuming only 50 mA of idle current. The channel switching is performed via a serial digital control (which can accommodate "daisy chaining" of several devices) or via a parallel control, allowing updating of an individual output without reprogramming the entire array. The AD8110/AD8111 is packaged in an 80-lead LQFP package and is available over the extended industrial temperature range of 40°C to +85°C.
The AD8110 and AD8111 are high-speed 16 × 8 video crosspoint switch matrices. They offer a 3 dB signal bandwidth greater than 260 MHz, and channel switch times of less than 25 ns with 1% settling. With 78 dB of crosstalk and 97 dB isolation (@ 5 MHz), the AD8110/AD8111 are useful in many high-speed applications. The differential gain and differential

NOTES 1Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2 S p e c i f i c a t i o n is for device in free air (T = 25°C): A 80-lead plastic LQFP (ST): JA = 48°C/W.
Exceeding a junction temperature of 175°C for an extended period can result in device failure. While the AD8110/AD8111 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature (150°C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves shown in Figure 3.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD8110/AD8111 is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic e n c a p s u l a t e d devices is determined by the glass transition temperature of the plastic, approximately 150°C. Temporarily exceeding this limit may cause a shift in parametric performance due to a change in the stresses exerted on the die by the package.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8110/AD8111 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
