#158104 - ESD protected keypad |
Need a 16 button keypad for this 8051 project but it must be able to handle the 20 Kv zapper the testing lab uses without damaging the MCU.
Is there such a thing as a totally metal keypad that I could ground to protect the MCU or is there some kind of ESD device I could connect to each of the (remote via cable) keypads lines to protect the MCU? |
