MPC100

The MPC100 consists of four identical monolithic inte­grated open-loop buffer amplifiers, which are con­nected internally at the output. The unidirectional trans­mission path consists of bipolar complementary buffers,
which offer extremely high output-to-input isolation.
The MPC100 multiplexer enables one of the four input
channels to connect 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 250MHz at 1.4Vp-p
signal level, high linearity and low distortion, and low
input voltage noise of 4nV/√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 space­saving SO-14 and DIP packages. Both are designed
and specified for operation over the industrial tem­perature range (–40°C to +85°C.)

ELECTROSTATIC
DISCHARGE SENSITIVITY

Electrostatic discharge can cause damage ranging from per­formance degradation to complete device failure. Burr-Brown
Corporation recommends that all integrated circuits be handled
and stored using appropriate ESD protection methods.

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 published speci­fications.
