Description

The MDE2574 is a series of 4-digit LED displays with common anode listed in the Agenda radioelectronistului (2nd edition, 1989) among the optoelectronic devices made in Romania by Microelectronica [1]. Its codes (MDE2574R and MDE2574V) are in the Variants table.

The Agenda lists them in the group „MDE 2574 R (V)”; the last letter of the code gives the colour (R = red, P = orange, G = yellow, V = green) [1].

The Agenda describes them as: „Afișor cu LED-uri, 4 digiți, anod comun, roșu (R), verde (V)” [1].

In the scan the first digit of the display drawing carries handwritten segment letters.
