MAX13046E Datasheet, PDF (1/15 Pages) Maxim Integrated Products – Single- and Dual-Bidirectional Low-Level Translator

19-4149; Rev 1; 8/08
Single- and Dual-Bidirectional
Low-Level Translator
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,
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.
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.
