General Description

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, VCCand VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VLside of the device appears as a high-voltage logic signal on the VCCside of the device, and vice-versa. The MAX3374E/MAX3375E/ MAX3376E/MAX3379E and MAX3390E–MAX3393E unidirectional level translators level shift data in one direction (VL→ VCCor VCC→ VL) on any single data line. The MAX3372E/MAX3373E and MAX3377E/MAX3378E bidirectional level translators utilize a transmission-gatebased design (Figure 2) to allow data translation in either direction (VL↔ VCC) on any single data line. The MAX3372E–MAX3379E and MAX3390E–MAX3393E accept VLfrom +1.2V to +5.5V and VCCfrom +1.65V to +5.5V, making them ideal for data transfer between lowvoltage 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 Timing Characteristics.)

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