Problem: So I have ran across the following part and I simply don't know what it is. I tried searching for if you will a description of it. (I.E. two diodes on top of each other pointing opposite directions) This of course did not help.

Help: So what is this? idk

Advice: So when you run across something you don't know how do you solve this? I mean besides using context clues from the circuit. If its just a symbol and you can not identify the part. Advice?

Notes: It is from the block diagram of the datasheet of the MC14468.

  • Can you say a bit about the context of the symbol? Was it in an analog circuit or a digital circuit? Was there a reference designator (U1, IC3, etc.)? Was there a part number associated with it? – John Honniball Nov 19 '14 at 22:07

    Google image search lets you drop an image to search for visually similar things. Sometimes that's helpful, but in this case it looks like that component is a chair. – Phil Frost Nov 19 '14 at 22:10
  • It is from the block diagram of the datasheet of the MC14468. Link - http://www.freescale.com/files/analog/doc/data_sheet/MC14468.pdf – tman Nov 19 '14 at 22:11
  • @IgnacioVazquez-Abrams I guess thank you! Im also curious how to solve this question going forward though. In the end I am not sure how I would have found that answer. I do not view it as 4 triangles and rather 2 diodes. Thanks though! – tman Nov 19 '14 at 22:17
  • The only advice I can provide is to find a diagram with a large number of symbols and look hard. – Ignacio Vazquez-Abrams Nov 19 '14 at 22:19

I remember seeing a similar question here (but couldn't find it). The component seems to be a transmission gate, or analog switch. (http://en.wikipedia.org/wiki/Transmission_gate)

Google-ing it helps you find the schematic: https://www.google.hu/search?q=transmission+gate+symbol
