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-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 chan...
