What is a totem pole driver?
A totem pole driver or output stage is a loose term used to mean that the output is driven actively in both the high and low directions.
How does a totem pole circuit work?
Totem pole consists of pull up and pull down transistors along with the diode resistor. Totem pole operates at high speed. The two transistors used drives a high output and another pulls it down in an Integrated circuit.
What is a totem pole configuration?
A2A 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 the disadvantage of totem pole?
The wired AND operation cannot be done in the totem – pole TTL because when one output is LOW, the other at HIGH state. As both the output are ANDed, large current flow from supply to ground through transistors.
What’s another word for totem pole?
n. emblem, column, pillar.
When would you use a MOSFET?
The infinite high input impedance makes MOSFETs useful for power amplifiers. The devices are also well suited to high-speed switching applications. Some integrated circuits contain tiny MOSFETs and are used in computers. Because the oxide layer is so thin, the MOSFET can be damaged by built up electrostatic charges.
What is the need of totem pole output?
The Totem Pole output is going to sink/source less current then a Push-Pull output is capable of sinking or sourcing. The other major difference is the output voltage between the two. The Totem Pole is a 5V DC signal only, where the Push Pull will follow the input voltage.
What are the advantages of totem-pole Output?
Advantages
- Low power dissipation.
- Fast rise time at the output of the TTL.
