Hey, first time poster, love this site by the way.
I was looking for a logic gate schematic to help in my project to convert binary input to a 7 segment digital output and i came across a logic gate i had never seen before.
The one i do not recognize is the one with 3 inputs that looks like 2 hour glasses side-by-side.
If someone could tell me what the gate is or has a better schematic it would really help me out.
Thanks

 

It is not a gate, look here

Hello,

Do you have the partnumber of the circuit used?
It might be a bidirectional buffer of some kind.

Well in my country this symbol is use for CMOS Swich (4066) or Transmission gate.
