♦ 100MHz Unity-Gain Bandwidth
The MAX463–MAX470 s e rie s of two-c ha nne l,
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 appli-
cations. 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).
♦ 90MHz Bandwidth with 2V/V Gain
♦ 0.01%/0.03° Differential Gain/Phase Error
♦ Drives 50Ω and 75Ω Back-Terminated Cable Directly
♦ Wide Output Swing:
±2V into 75Ω
±2.5V into 150Ω
♦ 300V/µs Slew Rate (2V/V gain)
♦ 20ns Channel Switching Time
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
♦ Logic Disable Mode:
High-Z Outputs
Reduced Power Consumption
for A = 2V/V amplifiers), and a bandwidth of 100MHz
V
♦ Outputs May Be Paralleled for Larger Networks
♦ 5pF Input Capacitance (channel on or off)
(90MHz for A = 2V/V buffers). Channel selection is
V
controlled by a single TTL-compatible input pin or by a
microprocessor interface, and channel switch time is
only 20ns.
______________Ord e rin g In fo rm a t io n
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 out-
put swing of ±2V into 75Ω.
