A Class B push–pull output driver using a pair of complementary PNP and NPN bipolar junction transistors configured as emitter followers. A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance ...
The diamond buffer or diamond follower is a four-transistor, two-stage, push-pull, translinear emitter follower, or less commonly source follower, in which the input transistors are folded, or placed upside-down with respect to the output transistors. [3]
I3C uses open-drain mode when necessary for compatibility, but switches to push-pull outputs whenever possible, and includes protocol changes to make it possible more often than in I²C. SCL is a conventional digital clock signal, driven with a push-pull output by the
Push–pull power amplifier. The push–pull output circuit shown is a simplified variation of the Williamson topology, which comprises four stages: a SET input stage to buffer the input and give some voltage gain. a phase splitter, usually of the cathodyne or "concertina" type.
Output column – a blank cell means a "totem pole" output, also known as a push–pull output, with the ability to drive ten standard inputs of the same logic subfamily (fan-out N O = 10). Outputs with higher output currents are often called drivers or buffers.
In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without interference from the ...
All parts in this section have normal inputs and push-pull outputs, unless stated differently. One input voltage translation gates: 40109 = Quad Buffer (dual power rails) (logic can step up or down, depending on power rail choice) 4504 = Hex Buffer (dual power rails) (logic can step up or down, depending on power rail choice) One input logic gates:
In a fully symmetrical push-pull circuit two Darlington pairs are connected as emitter followers driving the output from the positive and negative supply: an NPN Darlington pair connected to the positive rail providing current for positive excursions of the output, and a PNP Darlington pair connected to the negative rail providing current for ...
