For an NPN open emitter output, the collector is connected to the positive voltage rail, so the emitter outputs a high voltage when the transistor is on and is hi-Z when off. For a PNP open emitter output, the collector is connected to the low voltage supply, so the emitter outputs a low voltage when the transistor is on and is hi-Z when off.
The transistor continuously monitors V diff and adjusts its emitter voltage to equal V in minus the mostly constant V BE (approximately one diode forward voltage drop) by passing the collector current through the emitter resistor R E. As a result, the output voltage follows the input voltage variations from V BE up to V +; hence the name ...
English: Two inputs are connected to open-collector buffers. If a buffer's input is high, the buffer will be in a high-impedance output state. If a buffer's input is low, the buffer will connect to ground. If all inputs are high, the output will be pulled high by the pull-up resistor.

President-elect Donald Trump's criminal conviction should be tossed out because he was elected president, his lawyers say.. In a letter made public Wednesday, defense attorneys Todd Blanche and ...
English: Four inputs are connected to open-collector buffers (such as the SNx407 IC). If a buffer's input is high, the buffer will be in an high-impedance output state. If a buffer's input is low, the buffer will connect to ground.
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
Kevin Costner recently told the Daily Mail that he hasn’t given the “Yellowstone” series finale “any thoughts” since it aired on Dec. 15. Costner, whose “Yellowstone” character John ...
