Schottky-diode FET logic

Schottky-diode FET logic

[′shät·kē ¦dī‚ōd ¦ef¦ē¦tē ′läj·ik]
(electronics)
A logic gate configuration used with gallium-arsenide field-effect transistors operating in the depletion mode, in which very small Schottky diodes at the gate input provide the logical OR function and the level shifting required to make the input and output voltage levels compatible. Abbreviated SDFL.
