1 / 25 page 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, 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 unidi- rectional level translators level shift data in one direction (VL → VCC or VCC → VL) on any single data line. The MAX3372E/MAX3373E and MAX3377E/MAX3378E bidi- rectional 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 +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 short- circuit protection, and ±15kV ESD protection on the VCC side for greater protection in applications that route sig- nals 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 pack- ages. The MAX3377E/MAX3378E/MAX3379E and MAX3390E–MAX3393E are quad level shifters avail- able in 3 x 4 UCSP and 14-pin TSSOP packages. ________________________Applications 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 Equipment Features o Guaranteed Data Rate Options 230kbps 8Mbps (+1.2V ≤ VL ≤ VCC ≤ +5.5V) 10Mbps (+1.2V ≤ VL ≤ VCC ≤ +3.3V) 16Mbps (+1.8V ≤ VL ≤ VCC ≤ +2.5V and +2.5V ≤ VL ≤ VCC ≤ +3.3V) o Bidirectional Level Translation (MAX3372E/MAX3373E and MAX3377E/MAX3378E) o Operation Down to +1.2V on VL o ±15kV ESD Protection on I/O VCC Lines o Ultra-Low 1µA Supply Current in Three-State Output Mode o Low-Quiescent Current (130µA typ) o UCSP, SOT, and TSSOP Packages o Thermal Short-Circuit Protection ±15kV ESD-Protected, 1µA, 16Mbps, Dual/Quad Low-Voltage Level Translators in UCSP ________________________________________________________________ Maxim Integrated Products 1 THREE-STATE I/O VL1 I/O VL2 1 2 8 7 I/O VCC1 VCC GND VL I/O VCC2 SOT23-8 TOP VIEW 3 4 6 5 MAX3372E/ MAX3373E Pin Configurations 19-2328; Rev 3; 9/03 For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com.
