Device voltage thresholds chart [Infographic]
posted June 9 2012 7:09.01 by Giorgos Lazaridis




Here is a very nice chart that i found when i was searching around the net for information regarding the voltage level thresholds of various devices. Since i've been messing around with low voltage mirocontrollers, i need to know whether the 3.3V output is recognizable as a HIGH input for other 5V devices. From the chart it is obvious that although a TTL will recognize 3.3V as V In, a CMOS won't.
Generally, care must be taken when working with different voltage devices.
