The Interchange Jumper

– JMP8

The ISO5500 device is similar to other devices currently available from other manufacturers. One of the

similar devices uses pin 15 as an output driver for an LED. The TI ISO5500 uses pin 15 as a VEE (GND)

connection. If the user wishes to install a different device onto the PCB, and that device does not use pin

15 as a VEE connection, the user can simply use the jumper short from JMP8. This opens the pin 15

connection to VEE. JMP8 can then be used as a test point for the output signal on pin 15.
