Semiconductor integrated circuit device capable of externally monitoring internal voltage |
摘要 |
A test on a desired internal voltage is easily and accurately conducted without increasing current dissipation or the number of pads. A driving circuit receiving a reference voltage from a reference voltage generating circuit has a high input impedance and low output impedance, and generates a voltage substantially at the same voltage level as the reference voltage received, and transmits the generated voltage to a pad with a current driving capability larger than the driving current capability of the reference voltage generating circuit. |
