• Pin Protection
• Pin Impedance
• Reversed Pins 7 and 8

Answer: All interface pins have protective diodes and series resistors.

Question: What is the impedance of pins 7, 8, 9, and 10?

Answer: The impedances are as follows:

• Pin 7: 11k ohm
• Pin 8: 100k ohm during normal operation
• Pin 9 and Pin 10: 10k ohm

Question: Will the power supply be damaged if pins 7 and 8 are accidently reversed?

Answer: There should be no damage is Pins 7 and 8 are accidently reversed.
