MAX3378EEUD+T

The MAX3372E–MAX3379E and MAX3390E–MAX3393E ±15kV ESD-protected level translators provide the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, V_CC and V_L, set the logic levels on either side of the device. A low-voltage logic signal present on the V_L side of the device appears as a high-voltage logic signal on the V_CC side of the device, and vice-versa. The MAX3374E/MAX3375E/MAX3376E/MAX3379E and MAX3390E–MAX3393E unidirectional level translators level shift data in one direction (V_L → V_CC or V_CC → V_L) on any single data line. The MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gate-based design (Figure 2 in the full data sheet) to allow data translation in either direction (V_L ⇔ V_CC) on any single data line. The MAX3372E–MAX3379E and MAX3390E–MAX3393E accept V_L from +1.2V to +5.5V and V_CC from +1.65V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems.
