1	edu	what is meant by totempole There are two or more transistors between the power supply pin and ground. One pulls the output towards the supply and the other pulls the output towards ground (but not at the same time). This colourful term comes from the red indians of North America carving faces on a tree trunk.	2008/8/26 05:21

2	chdd	what is meant by totempole "totempole "is a configulation in TTL circuit.the named comes as one transistor is upon another transistor.	2008/8/26 05:21

3	htc2498	what is meant by totempole "Totempole" output also distinguishes itself from other drivers with a passive high or low. One of the states there is ruled by a resistor (or current source). Totempole outputs can never be or'ed or and'ed together, while the passive ones can.	2008/8/26 05:21

6	gao51755775	what is meant by totempole A totem pole consists of two transistors, which are driven complementary.One transistor pulls the output voltage down, the other transistor pulls the output voltage up. Depending on the desired output, only one of the two transistors is conducting. Two totem pole outputs should never be tied together. If two totem pole outputs are connected, a shortcut occurs if they carry different digital signals (0/1 or 1/0) , it means If one output voltage is high and the other low , the "pullup" transistor of the first gate fights the "pulldown" transistor of the other. This is one of the most frequent causes of burned out chips	2008/8/26 05:21
