Question

why wired and gates is not possible in totem-pole configuration?

Answer 1

Answer:

connection are used, then a large current from supply +V will flows to ground through high state gate transistor and low state gate transistor. Thus, large current will flow which damages the output transistors of totem pole TTL arrangement.

Answer 2
