MAX3372E–MAX3379E/ MAX3390E–MAX3393E ±15kV ESD …

1 General DescriptionThe MAX3372E MAX3379E and MAX3390E MAX3393E 15kv ESD- protected level translators provide the level shifting necessary to allow data transfer in a multivolt-age 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 uni-directional level translators level shift data in one direc-tion (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 (Figure 2) to allow data translation in either direction (VL VCC) on any single data line. The MAX3372E MAX3379E and MAX3390E MAX3393E accept VL from + to + and VCC from + to + , making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage devices in the MAX3372E MAX3379E, MAX3390E MAX3393E family feature a three-state output mode that reduces supply current to less than 1 A, thermal shortcircuit protection, and 15kv ESD protection on the VCC side for greater protection in applications that route signals externally.

2 The MAX3372E/MAX3377E operate at a guaranteed data rate of 230kbps. Slew-rate limit-ing reduces EMI emissions in all 230kbps devices. The MAX3373E MAX3376E/MAX3378E/MAX3379E and MAX3390E MAX3393E operate at a guaranteed data rate of 8 Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible. (See the Timing Characteristics table.)The MAX3372E MAX3376E are dual level shifters avail-able in 3 x 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 x 4 UCSP, 14-pin TDFN, and 14-pin TSSOP SPI, MICROWIRE, and I2C Level Translation Low-Voltage ASIC Level Translation Smart Card Readers Cell-Phone Cradles Portable POS Systems Portable Communication Devices Low-Cost Serial Interfaces Cell Phones GPS Telecommunications EquipmentFeatures Logic-Level Translators Simplify Design by Enabling Data Transfer Between Lower and Higher Voltage Systems Operation Down to + on VL Guaranteed Data Rate Options 230kbps 8 Mbps (+ VL VCC + ) 10 Mbps (+ VL VCC + ) 16 Mbps (+ VL VCC + and + VL VCC + ) Bidirectional Level Translation (MAX3372E/MAX3373E and MAX3377E/MAX3378E) Low Power Consumption Reduces Thermal Dissipation Quiescent Current (130 A typ)
