CMOS logic defines its logic thresholds as a percentage of supply voltage, which with a 5V supply puts the logic 1 threshold of 70% well above the 3.3V logic 1. Some CMOS ICs such as the 74HC4053 ...
He’s wondering if the ESP8266 is 5V tolerant after all. If it is, great. We don’t need level converters, and interfacing the ESP to USB TTL serial adapters becomes much easier. Yes ...
