Dual Bidirectional Low-Level
Translator in µDFN
General Description
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 trans-
mission-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 pro-
tection, and ±15kV ESD protection on the VCC side for
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.
The MAX3397E is available in an 8-pin µDFN package
andwww.DataSheet4U.com specified over the extended -40°C to +85°C oper-
ating temperature range.
