MAX13046E/MAX13047E
Detailed 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,
V
CC
and V
L
, 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
L
↔ V
CC
) on any single data line. The
MAX13046E/MAX13047E accept V
L
from +1.1V to the
minimum of either +3.6V or (V
CC
+ 0.3V) and V
CC
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
V
CC
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. See the
