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 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).
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 A
(90MHz for A
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 out-
put swing of ±2V into 75Ω.
Devices offered in this series are as follows:
