EVALUATION KIT AVAILABLE
MAX14595
Low-Power Dual-Channel Logic-Level Translator
General Description
The MAX14595 is a dual-channel, bidirectional logic-
level translator designed specifically for low power
consumption making it suitable for portable and battery-
powered equipment. Externally applied voltages, V_CC
and V_L, set the logic levels on either side of the device. A
logic signal present on the V_L side of the device appears
as the same logic signal on the V_CC side of the device,
and vice-versa.
The device is optimized for the I²C bus as well as the
management data input/output (MDIO) bus where often
high-speed, open-drain operation is required. When TS
is high, the device allows the pullup to be connected to
the I/O port that has the power. This allows continuous
I²C operation on the powered side without any disruption
while the level translation function is off.
The part is specified over the extended -40NC to +85NC
temperature range, and is available in 8-bump WLP and
8-pin TDFN packages.
