- 3- to 8 line decoder / demultiplexer (74HCT138)
-
- This IC decodes one-of-eight lines dependent on the
- conditions at the three binary select inputs and
- the three enable inputs. Two active-low and one
- active-high enable inputs reduce the need for
- external gates or gates when expanding. A 24-line
- decoder can be implemented without external inverters
- and a 32-line decoder requires only one inverter.
- An enable input can be used as a data input for
- demultiplexing applications.

- You can drag this component to another position
- by clicking inside the body of the port, hold
- the mouse button, move to the new position,
- and release the mouse button.
