It notices technical: You
use the integrated correct only, brought in the chart not the series: SN7414 (standard - 10mW), SN74H14 (High
speed - 22mW), SN74L14 (Low power - 1mW). In alternative you can replace it with SN74S14 (Schottky
- 19mW).
Note: We are verifying the course and the effectiveness of
some fotodiodis and fototransistor. We have inserted the specific techniques of the
components however D4 and T4 used for the first tests. Don't be from to exclude technical
changes aimed at to increase the course of the device! If you desire to be told, send an
e-mail to me to the address under brought and you complete the object with: Infrared helps.
