#20384 - RE: what is float state-phillip |
CMOS input are very Hi-Z. As you probably know the CMOS structure uses a P and N Mos transistor architecture. Any leakage or external potentials can cause an unterminated input to start to float to the linear region where both the P and N channel devices are conducting. The fact that it floats to this linear region is because both the devices will "self-bias" to approx. 1/2 VCC.
