![]() It is determined by the upper output transistor V3 operating in active region as an emitter follower. The main advantage of TTL with a “totem-pole” output stage is the low output resistance at output logical “1”. What is the advantage of the totem-pole connection? Why do we use totem pole output?Ī Totem-Pole output is often used for logic gates and some op-amps because it allows the output to approach ground potential, or zero volts. The main advantage of TTL with a “totem-pole” output stage is the low output resistance at output logical “1”, also, the addition of an active pull up the circuit in the output of the Gate results in the reduction of propagation delay. The purpose of the totem pole configuration is to supply enough current to guarantee that the output goes up to a sufficiently high voltage when pulled up and to sink enough current to guarantee that the output goes down to a sufficiently low voltage when pulled down so that it drives the following input or inputs … What is a totem-pole What is its advantage? The two transistors used drives a high output and another pulls it down in an Integrated circuit. Totem pole consists of pull up and pull down transistors along with the diode resistor. Logic operation is the same as the open collector output. Totem Pole means the addition of an active pull up the circuit in the output of the Gate which results in a reduction of propagation delay. ![]()
