Voltage Level Translator 9-Pin UCSP

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, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VL side of the device appears as a high-voltage logic signal on the VCC side of the device, and vice-versa. The MAX3374E/MAX3375E/MAX3376E/MAX3379E and MAX3390E–MAX3393E unidirectional level translators level shift data in one direction (VL ? VCC or VCC ? VL) 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 (VL ? VCC) on any single data line. The MAX3372E–MAX3379E and MAX3390E–MAX3393E accept VL from +1.2V to +5.5V and VCC 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 VCC 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 x 3 UCSP, 8-pin TDFN, and 8-pin SOT23 packages. The MAX3377E/MAX3378E/MAX3379E and MAX3390E–MAX3393E are quad level shifters available in 3 x 4 UCSP, 14-pin TDFN, and 14-pin TSSOP packages.
