说明

The MAX463–MAX470 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 150Ω loads (75Ω back-terminated cable).

Input capacitance is typically only 5pF, and channel-to-channel crosstalk is better than 60dB, accomplished by surrounding all inputs with AC ground pins. The on-board 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 buffer-amplifier gains of 1V/V or 2V/V for 75Ω back-terminated applications. Output amplifiers have a guaranteed output swing of ±2V into 75Ω.
