MAXIM MAX3379EEUD+

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 to allow data translation in either direction 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 short-circuit 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.

The MAX3372E–MAX3376E are dual level shifters available in 3×3 UCSP, 8-pin TDFN, and 8-pin SOT23-8 packages. The MAX3377E/MAX3378E/MAX3379E and MAX3390E–MAX3393E are quad level shifters available in 3×4 UCSP, 14-pin TDFN, and 14-pin TSSOP packages.
