MAX469

The 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 150½ loads (75½ 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/s slew rate (300V/s 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.
