MAX14595
Low-Power Dual-Channel Logic-Level Translator
S Meets Industry Standards
General Description
ꢀI2C Requirements for Standard, Fast, and High*
Speeds
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, VCC
and VL, set the logic levels on either side of the device. A
logic signal present on the VL side of the device appears
as the same logic signal on the VCC 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.
