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 channel switch time is only 20ns.
For design flexibility, devices are offered with bufferamplifier gains of 1V/V or 2V/V for 75Ω back-terminated applications.
Output amplifiers have a guaranteed output swing of ±2V into 75Ω.
