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 opposing currents in the primary windings always balance but the whole primary "sees" the complete sinewave. In this manner, a sinewave is able to be generated while allowing the transistors to switch alternately fully on and off in push-pull mode. This is the only resemblance to the Royer converter.
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.
English: Circuit diagram of a push-pull DC to DC converter. This is used in battery-powered electronic devices such as laptops to convert DC power to a higher voltage. The switches (left) represent pairs of switching transistors, with the driving circuits omitted. They are switched simultaneously at a high frequency of 10 - 80 kHz They switch ...
A 555 timer can act as an active-low SR latch (though without an inverted Q output) with two outputs: output pin is a push-pull output, discharge pin is an open-collector output (requires a pull-up resistor). For the schematic on the right, a Reset input signal connects to the RESET pin and connecting a Set input signal to the TR pin.
A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC power supply. The distinguishing feature of a push-pull converter is that the transformer primary is supplied with current from the input line by pairs of transistors in a symmetrical push-pull circuit. The ...

To solve the problem with the high output resistance of the simple output stage the second schematic adds to this a "totem-pole" ("push–pull") output. It consists of the two n-p-n transistors V 3 and V 4, the "lifting" diode V 5 and the current-limiting resistor R 3 (see the figure on the right).
