![]() ![]() ![]() Hence it is known as fastest logic family. ➨It has average propagation delay time ( 1 to 4 ns ) better compare to both TTL and CMOS. What is advantage of ECL over others?įollowing points summarize ECL advantages over TTL and CMOS: ➨It has fanout of 25 which is better than TTL and less then CMOS. Thus, large current will flow which damages the output transistors of totem pole TTL arrangement. What is totem pole? Totem pole basically an output driver circuit use to convert one level of voltage into another level of voltage. Why totem pole outputs cannot be connected together connection are used, then a large current from supply +V will flows to ground through high state gate transistor and low state gate transistor. It signifies the person who rises above the petty details of daily life to take in the big picture. It protects the spirit and the body, representing health and wholeness of being. The majestic Eagle is strength and vision. 1 Can anyone please explain why totempole outputs should not be connected together what is the solution SgtWookie Joined 22,230 2 If you tie two totem-pole outputs together, they will 'fight to the death' if they are set to different logic levels. Neither low power dissipation nor high speed A.īoth low power dissipation and high speed What is the major advantage of ECL logic?Ī major advantage of ECL logic over TTL and CMOS is _….Exercise :: Logic Gates – Filling the Blanks. Output stage of Open collector consists of only pull down transistor. Output stage of totem pole circuit consists of pull-up transistor, diode resistor and a pull down transistor. ![]() Logic operation is the same as the open collector output. Totem Pole 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. ![]()
