The MPC104 consists of two identical monolithic,
integrated, open-loop buffer amplifiers, which are
connected internally at the output. The bipolar complementary buffers form a unidirectional transmission
path and offer extremely high output-to-input isolation. The MPC104 multiplexer enables the user to
connect one of two input signals to the output. The
output of the multiplexer is in a high-impedance state
when no channel is selected. When one channel is
selected with a digital “1” at the corresponding SEL
input, the component acts as a buffer with high input
impedance and low output impedance.
The wide bandwidth of over 210MHz at 1.4Vp-p
signal level, high linearity and low distortion, and low
input voltage noise of 5nV/√Hz make this crosspoint
switch suitable for RF and video applications. All
performance is specified with ±5V supply voltage,
which reduces power consumption in comparison with
±15V designs. The multiplexer is available in a spacesaving 8-pin SO and DIP packages. Both are designed
and specified for operation over the industrial temperature range (–40°C to +85°C.)
Wide-Bandwidth
2 x 1 VIDEO MULTIPLEXER
DESCRIPTION
The MPC104 is a wide-bandwidth, 2-to-1 channel
video signal multiplexer, which can be used in a wide
variety of applications.
It was designed for wide-bandwidth systems, including high-definition television and broadcast equipment. Although it is primarily used to route video
signals, the harmonic and dynamic attributes of the
MPC104 also make it appropriate for other analog
signal routing applications such as radar, communications, computer graphics, and data acquisition systems.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
