MAX3397E 19-0771 Rev 0 4/07 Dual Bidirectional Low-Level Translator in DFN General Description Features The MAX3397E 15kV ESD-protected bidirectional Bidirectional Level Translation level translator provides level shifting for data transfer in Guaranteed Data Rate a multivoltage system. Externally applied voltages, V CC 8Mbps (+1.2V V V +5.5V) and V , set the logic levels on either side of the device. L CC L A logic-low signal present on the V side of the device 16Mbps (+1.8V V V +3.3V) L L CC appears as a logic-low signal on the V side of the CC Extended ESD Protection on the I/O V Lines CC device, and vice versa. The MAX3397E utilizes a trans- 15kV Human Body Model mission-gate-based design to allow data translation in 15kV Air-Gap Discharge per IEC 61000-4-2 either direction (V V ) on any single data line. The L CC 8kV Contact Discharge per IEC 61000-4-2 MAX3397E accepts V from +1.2V to +5.5V and V L CC from +1.65V to +5.5V, making the device ideal for data Enable/Shutdown transfer between low-voltage ASICs/PLDs and higher Ultra-Low 1A Supply Current in Shutdown Mode voltage systems. 8-Pin DFN Package The MAX3397E features a shutdown mode that reduces supply current to less than 1A, thermal short-circuit pro- tection, and 15kV ESD protection on the V side for CC greater protection in applications that route signals exter- nally. 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. Ordering Information The MAX3397E is available in an 8-pin DFN package and specified over the extended -40C to +85C oper- TEMP PIN- TOP PKG ating temperature range.
