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.

All devices in the MAX3372E–MAX3379E, MAX3390E–MAX3393E family feature a three-state output mode that reduces supply current to less than 1µA, thermal shortcircuit protection, and ±15kV ESD protection on the V_CC side for greater protection in applications that route signals externally. The MAX3372E/MAX3377E operate at a guaranteed data rate of 230kbps. Slew-rate limiting reduces EMI emissions in all 230kbps devices. The MAX3373E–MAX3376E/MAX3378E/MAX3379E and MAX3390E–MAX3393E operate at a guaranteed data rate of 8Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible. (See the Timing Characteristics table in the full data sheet.)
