A Totem Pole output is essentially the same as a Push Pull output; however, it is the terminology commonly used when referring to a TTL device. The major difference between it and a Push Pull is the amount of current that it can sink or source. 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.
