MAX14611
Quad Bidirectional Low-Voltage
Logic-Level Translator
General Description
The MAX14611 is a quad bidirectional logic-level transla-
tor that provides the level shifting necessary to allow data
transfer in a multivoltage system. Externally applied volt-
ages, V_CC and V_L, set the logic levels on either side of
the device. A low-voltage logic signal present on the V_L
side of the device appears as a high-voltage logic signal
on the V_CC side of the device, and vice-versa.
The device is ideal for I²C bus as well as MDIO bus appli-
cations where open-drain operation is often required. The
device features a three-state output mode (TS). Drive TS
high to connect the pullup to the powered I/O port. This
allows for continuous, undisrupted I²C operation on the
powered side of the device while the level translation
function is off. The MAX14611 is a pin-to-pin compatible
upgrade to the MAX3378E in the TDFN package.
The MAX14611 features enhanced high-electrostatic-
discharge (ESD) protection on all I/OVCC_ ports up to
±6kV HBM. The device operates over the -40NC to +85NC
extended temperature range and is available in 3mm x
3mm, 14-pin TDFN and 4.9mm x 5.1mm, 14-pin TSSOP
packages.
