General Description

The MAX14591 is a dual-channel, bidirectional logic-

level translator with the level shifting necessary to allow

data transfer in a multivoltage system. Externally applied

of the device, and vice-versa.

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

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.
