Abstract: front page image
(EN)An interface circuit (10a) is a circuit that receives an input signal VIN having a high potential VIH as a high level and having a low potential VIL as a low level and that outputs an output signal VOUT having a high potential VOH as a high level and having a low potential VOL as a low level. The interface circuit (10a) is provided with a polarity control unit (1a) for controlling whether to in-phase the level of the output signal VOUT with the input signal VIN or whether to invert the polarity of the output signal VOUT with respect to the input signal VIN depending on which of the high potential VIH and the low potential VIL is a GND potential.
(FR)La présente invention concerne un circuit d'interface (10a), lequel est un circuit qui reçoit un signal d'entrée (VIN) ayant un potentiel haut (VIH) en tant que niveau haut et ayant un potentiel bas (VIL) en tant que niveau bas et qui émet un signal de sortie (VOUT) ayant un potentiel haut (VOH) en tant que niveau haut et ayant un potentiel bas (VOL) en tant que niveau bas. Le circuit d'interface (10a) est pourvu d'une unité de commande de polarité (1a) permettant de vérifier s'il faut mettre en phase le niveau du signal de sortie (VOUT) avec le signal d'entrée (VIN) ou s'il faut inverser la polarité du signal de sortie (VOUT) par rapport au signal d'entrée (VIN) selon celui qui est un potentiel GND parmi le potentiel haut (VIH) et le potentiel bas (VIL).
