TECHNICAL NOTES
1. Proper operation of the MX-850 multiplexer is dependent
upon good board layout and connection practices. Bypass
supplies as shown in the connection diagrams. Mount
bypass capacitors directly to the supply pins whenever
possible.
2. All grounds pins (9, 11, 13) should be tied together and
connected to ground as close to the multiplexer as
possible.
3. When power is off, current limit input signals on pins 4, 5, 6,
and 7 to 20mA. Failure to current limit can cause
permanent damage to the device since, when powering up
or down it is possible that two switches might be on at the
same time. Excessive current (greater than 20mA) will flow
from the more positive input to the more negative input,
permanently damaging the device. Applications in which
the power supply for the multiplexer also powers the signal
sources may not require limiting resistors. See Figure 4.
