Signature indicating circuit |
摘要 |
A circuit for testing signatures at a pin in a CMOS device where this device is operable when it is powered by a voltage within the predetermined range. During the test mode, a task voltage whose magnitude is below that of any voltage in the operating range as applied so that parasitic diode turn-on is prevented.
