The MPC104 consists of two identical monolithic,

integrated, open-loop buffer amplifiers, which are

connected internally at the output. The bipolar comple-

mentary buffers form a unidirectional transmission

path and offer extremely high output-to-input isola-

tion. 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 space-

saving 8-pin SO and DIP packages. Both are designed

and specified for operation over the industrial tem-

perature 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, includ-

ing high-definition television and broadcast equip-

ment. 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, communica-

tions, computer graphics, and data acquisition sys-

tems.
