#175305 - You are wellcome Responding to: ???'s previous message |
..and You can simulate zener in Proteus - conected with cathode to INT0 and with anode to VSS rail of micro. For negative (to Vss) voltage will act as clamp diode, for positive voltages will limit voltage to Vz (relative to Vss).
So Vzener<=5.6V .As there are no ideal zeners - limiting will occur between 4 and 5.6V . Please, describe Your task/target more ( don't be afraid somebody will stole Your trade idea ), so we can help more. regards |
