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.
