MAX4141CSD
330MHz / 4x1 Precision Video Multiplexer
_______________General Description
The MAX4141 is a wideband 330MHz, 700V/µs 4x1
multiplexer optimized for high-definition, broadcast-
quality, composite (HDTV, NTSC, PAL, SECAM) video
switching arrays. The device includes four open-loop
buffer amplifiers with a 0.1dB gain flatness of 150MHz,
and enable and switch-control logic. The MAX4141
operates from ±5V supplies and features differential
phase and gain error of only 0.01°/0.01%. The ultra-low
switching glitch (less than 13mV) is positive to avoid
confusion with any sync pulses.
Ideal as a building block for large switch arrays, the
MAX4141 features a constant, high input impedance
and a disable function that puts the output into a high-
impedance state and reduces the operating current to
only 250µA. The open-loop architecture allows the out-
put to drive capacitive loads without oscillation.
Other key features include -66dB crosstalk (30MHz),
-74dB isolation (30MHz), less than 10mV offset voltage,
and a 110MHz full-power bandwidth (1.4Vp-p). The
MAX4141 is available in a 14-pin narrow SO package.

_______________Detailed Description
The MAX4141 video switch is manufactured with
Maxim’s proprietary complementary bipolar process
that yields high bandwidth and low capacitance. To
maintain a wide bandwidth, the MAX4141 incorporates
a straightforward structure of input and output buffers.
Make-before-break switching is employed to reduce
noise and glitches, even when switching from part to
part in large arrays. The input buffers provide a con-
stant, high input impedance. And, they prevent the
make-before-break action from feeding back to the
input and causing noise and/or glitches.
The design of the switching mechanism limits the
inevitable glitch to within 13mVp-p. In addition, the
glitch pulse is positive to avoid confusion with any neg-
ative sync pulses.
Unity-gain output buffers isolate other inputs from the
switching action of large multiplex arrays. These buffers
can drive 5kΩresistive loads. Load capacitance is lim-
ited only by system bandwidth requirements.
The MAX4141 does not contain buffer latches. The digi-
tal inputs control the switch transparently.
__________Applications Information
Grounding, Bypassing,
and PC Board Layout
In order to obtain the MAX4141’s full 330MHz bandwidth,
Microstrip and Stripline techniques are recommended in
most cases. To ensure your PC board does not degrade
the switch’s performance, it’s wise to design the board
for a frequency greater than 1GHz. Even with very short
runs, it’s good practice to use this technique at critical
points, such as inputs and outputs. Whether you use a
constant-impedance board or not, observe the following
guidelines when designing the board: Do not use wire-wrap boards, because they are too
inductive.Do not use IC sockets. They increase parasitic
capacitance and inductance. In general, surface-mount components have shorter
leads and lower parasitic reactance, and give better
high-frequency performance than through-hole com-
ponents. The PC board should have at least two layers, with
one side a signal layer and the other a ground plane. Keep signal lines as short and as straight as possi-
ble. Do not make 90°turns; round all corners. The ground plane should be as free from voids as
possible.
