MAX3397E

The MAX3397E features a shutdown mode that reduces supply current to less than 1A, 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. And it 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. See the Timing Characteristics table. The MAX3397E is available in an 8-pin DFN package and specified over the extended -40°C to +85°C operating temperature range.Within specific voltage domains, higher data rates are possible. 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 device utilizes a transmission-gate-based design to allow data translation in either direction (VL-VCC) on any single data line.

The features of MAX3397E can be summarized as (1)bidirectional level translation; (2)guaranteed data rate 8Mbps (+1.2V VL VCC +5.5V) 16Mbps (+1.8V VL VCC +3.3V); (3)extended ESD protection on the I/O VCC lines ±15kV human body model ±15kV air-gap discharge per IEC 61000-4-2 ±8kV contact discharge per IEC 61000-4-2; (4)enable/shutdown; (5)ultra-low 1A supply current in shutdown mode; (6)8-Pin DFN package.

The absolute maximum ratings of MAX3397E are (1)(All voltages referenced to GND.); (2)VCC, VL: -0.3V to +6V; (3)I/O VCC: -0.3V to (VCC + 0.3V); (4)I/O VL_ : -0.3V to (VL + 0.3V); (5)EN: -0.3V to +6V; (6)short-circuit duration I/O VL_, I/O VCC_ to GND: continuous; (7)continuous power dissipation (TA = +70°C) 8-Pin DFN (derate 4.8mW/°C above +70°C): 381mW; (8)operating temperature range: -40°C to +85°C; (9)storage temperature range: -65°C to +150°C; (10)lead temperature (soldering, 10s): +300°C.
