_______________General Description
T h e MAX463MAX470 series of two-channel, triple/quad buffered video switches and video buffers combines high-accuracy, unity-gain-stable amplifiers with high-performance video switches. Fast switching time and low differential gain and phase error make this series of switches and buffers ideal for all video applications. The devices are all specified for ±5V supply operation with inputs and outputs as high as ±2.5V when driving 150 loads (75 back-terminated cable). Input capacitance is typically only 5pF, and channel-tochannel crosstalk is better than 60dB, accomplished by surrounding all inputs with AC ground pins. The onboard amplifiers feature a 200V/µs slew rate (300V/µs for AV = 2V/V amplifiers), and a bandwidth of 100MHz (90MHz for AV = 2V/V buffers). Channel selection is controlled by a single TTL-compatible input pin or by a microprocessor interface, and channel switch time is only 20ns. For design flexibility, devices are offered with bufferamplifier gains of 1V/V or 2V/V for 75 back-terminated applications. Output amplifiers have a guaranteed output swing of ±2V into 75. Devices offered in this series are as follows:

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.
