PIC16F1823绝对最大电压

我的电压调节器失灵了，是我的错。未观察到最大电压（3.3V）。被喂养超过6伏特。当它失败时，它将输出电压完全输出出去。它喂养一个16F1823，它的绝对最大电压为6.5伏特。改变了稳压器并编程了16F1823。我的问题是，如果有人给这个芯片的+引脚提供一个不受控制的（因为我认为这是从稳压器中出来的PIC）6.5伏特和PIC是半导体，这会损坏PIC吗？PIC似乎运行良好，但我担心它可能会失败后，许多电源UPS，我应该改变它。-基思

                                                                            Had a voltage regulator fail on me; my fault. Didn't observe maximum voltage in (3.3V reg. Was being fed a little more than 6 volts). When it failed it sent the full inout voltage out the 'out' pin. It was feeding a 16F1823 which has an absolute max voltage of 6.5 volts. Changed up the regulator and programmed the 16F1823.
My question is, if someone fed the + pin of this chip an unregulated (because I think that's what was coming out of the regulator into the PIC) 6.5 volts and being that the PIC is a semiconductor, would this damage the PIC?
The PIC seems to be working fine but I'm worried that it might fail after numerous power ups and should I change it.-Keith
