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.
Open-emitter buffers connected as wired OR. See also: Diode logic § Active-high OR logic gate. The wired OR connection electrically performs the Boolean logic operation of an OR gate using open emitter or similar inputs (which can be identified by the ⎏ symbol in schematics) connected to a shared output with a pull-down resistor. This gate ...
A Minecraft server is a player-owned or business-owned multiplayer game server for the 2011 Mojang Studios video game Minecraft. In this context, the term "server" often refers to a network of connected servers, rather than a single machine. [ 1 ]
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 ...
Across the United States, Christmastime meals mean different things for different people. For residents of South Carolina, Christmas means it is time to roast oysters.

The heart of an I2L circuit is the common emitter open collector inverter. Typically, an inverter consists of an NPN transistor with the emitter connected to ground and the base biased with a forward current from the current source. The input is supplied to the base as either a current sink (low logic level) or as a high-z floating condition ...
Honey, they shrunk the catalogs. While retailers hope to go big this holiday season, customers may notice that the printed gift guides arriving in their mailboxes are smaller. Many of the millions ...
