19-0771; Rev 0; 4/07 KIT ATION EVALU LE B A IL A AV Dual Bidirectional Low-Level Translator in µDFN General Description Features ♦ Bidirectional Level Translation ♦ Guaranteed Data Rate 8Mbps (+1.2V ≤ VL ≤ VCC ≤ +5.5V) 16Mbps (+1.8V ≤ VL ≤ VCC ≤ +3.3V) ♦ Extended ESD Protection on the I/O VCC Lines ±15kV Human Body Model ±15kV Air-Gap Discharge per IEC61000-4-2 ±8kV Contact Discharge per IEC61000-4-2 ♦ Enable/Shutdown ♦ Ultra-Low 1µ A Supply Current in Shutdown Mode ♦ 8-Pin µ DFN Package MAX3397E 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 vol...
