When more "Temperature Sensing" inputs are needed two PCS5035 hybrids can be used as shown below

in Figure 4.

The outputs of the two PCS5035 hybrids can be wired together to produce a wired “OR” function. Each bank

of 5 inputs can then be separately controlled by its associated Enable input.

One application of this multiple input arrangement could be circuit board temperature monitoring using the

temperature characteristics of a PN (diode) junction. With a constant current to the diode sensor the diode

voltage can be a calibrated function of temperature. Diodes can be placed on or near vital electronic

components to monitor their case temperatures so that they can be shut down before a catastrophic

temperature failure occurs.
