General Description

The MAX13046E/MAX13047E ±15kV ESD-protected

bidirectional level translators provide level shifting for

data transfer in a multivoltage system. The MAX13046E

is a single-channel translator, and the MAX13047E is a

dual-channel translator. Externally applied voltages,

and V

, set the logic level on either side of the

device. The MAX13046E/MAX13047E utilize a transmis-

sion-gate-based design to allow data translation in

either direction (V

V

) on any single data line. The

MAX13046E/MAX13047E accept V

from +1.1V to the

minimum of either +3.6V or (V

+ 0.3V), and V

from

+1.65V to +5.5V, making these devices ideal for data

transfer between low-voltage ASICs/PLDs and higher

voltage systems.

The MAX13046E/MAX13047E feature a shutdown mode

that reduces supply current to less than 1µA thermal

short-circuit protection, and ±15kV ESD protection on the

side for enhanced protection in applications that

route signals externally. The MAX13046E/MAX13047E

operate at a guaranteed data rate of 8Mbps when push-

pull driving is used.

The MAX13046E is available in a 6-pin µDFN package,

and the MAX13047E is available in a 10-pin UTQFN.

Both devices are specified over the extended -40°C to

+85°C operating temperature range.
