MAX3397E：Dual Bidirectional Low-Level Translator in µDFN

Industry's Smallest Dual Bidirectional Logic-Level Translator

The MAX3397E ±15kV ESD-protected bidirectional level translator provides level shifting for data transfer in a multivoltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A logic-low signal present on the VL side of the device appears as a logic-low signal on the VCC side of the device, and vice versa. The MAX3397E utilizes a transmission- gate-based design to allow data translation in either direction (VL ↔ VCC) on any single data line. The MAX3397E accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, making the device ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. The MAX3397E features a shutdown 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 signals externally. The MAX3397E operates at a guaranteed data rate of 8Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible. See the Timing Characteristics table in the full data sheet. The MAX3397E is available in an 8-pin µDFN package and specified over the extended -40°C to +85°C operating temperature range.
