| Nov 7, 2013 at 16:07 | comment | added | pjc50 | Further upsetting this worldview: en.wikipedia.org/wiki/Logic_family It appears that a variant of ECL is still in use: focus.ti.com/lit/an/slla120/slla120.pdf but otherwise digital is almost always CMOS. | |
| Nov 7, 2013 at 15:45 | comment | added | pjc50 | "There are more things in heaven and earth than are dreamt of in your philosophy": TTL/CMOS is not an exhaustive classification! Semiconductor design has a fairly sharp demarcation between digital and analog, and analog devices may comprise whatever mix of bipolar and FET transistors they need to go the job. You're correct that you don't get TTL and CMOS on the same device, and a larger system will stick to one of those two, but there are more kinds of chip! It's a bit like saying all fruit is either apple or orange. | |
| Nov 7, 2013 at 15:42 | comment | added | user16307 | i mean in a circuitry why to use several different locig gates so one has to use interfaces to make them work together. where am i wrong?:( also isnt it cmos and ttl the most common ones? | |
| Nov 7, 2013 at 15:39 | comment | added | Anindo Ghosh | @user16307 Where did you get the impression that any component must be either TTL or CMOS? | |
| Nov 7, 2013 at 15:21 | comment | added | user16307 | intersting. i thought any component nowadays should be eirther ttl or cmos ?? | |
