Care e valoare tensiunii (MIN) la CMOS considerata 1?

Cu alte cuvinte: Care e tensiunea minima pe care CMOS-uri o discern ca 1 logic?Intreb din experienta practica. Am citit in datasheeturi. Dar vreau o parere a cuiva care lucreaza cu ele! Multumesc anticipat.

depinde de tensiunea de alimentare, de proces, de temperatura si de geometria portii. E safe sa spui ca tot ce e peste VDD-30% e considerat 1 logic De exemplu la pinii unui FPGA Spartan3 (VCCIO 3.3V)LVCMOS33 - 2.0 (VIH)LVCMOS33 - 0.8 (VIH)la un ATmega88 Input High Voltage, exceptXTAL1 and RESET pinsVCC = 1.8V - 2.4V 0.7VCCVCC = 2.4V - 5.5V 0.6VCCcel mai bine te uiti in datasheet la circuitul cu pricina.RR
