# How does the transistor topology look like for a gate of this logic inverter?

How does a single inverter gate of this hex inverter, look like in transistor level?

I don't mean the actual photo, but how does the transistor topology look like?

Does the BJT inverter (see below), with two resistors, represent the exact topology of the gate of a hex inverter IC?:

• It's not the exact topology of a gate in a hex inverter IC. For TTL, you might look at this TTL inverter/NAND discussion. – jonk Nov 13 '18 at 22:15
• At the very least Vout would have an emitter follower buffer. Normally it would have a totem-pole output as a buffer. – Sparky256 Nov 13 '18 at 22:28
