MAX14591
High-Speed, Open-Drain Capable
Logic-Level Translator
General Description
The MAX14591 is a dual-channel, bidirectional logiclevel translator with the level shifting necessary to allow
data transfer in a multivoltage system. 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.
The part is specified over the extended -40NC to +85NC
temperature range, and is available in 8-bump WLP and
8-pin TDFN packages.

Detailed Description
The MAX14591 is a dual-channel, bidirectional level translator. The device translates low voltage down to +0.9V on
the VL side to high voltage on the VCC side and vice-versa. The device is optimized for open-drain and high-speed
operation, such as I2C bus and MDIO bus.
The device has low on-resistance (17I max), which
is important for high-speed, open-drain operation. The
device also features internal pullup resistors that are
active when the corresponding power is on and TS is high.
Level Translation
For proper operation, ensure that +1.65V P VCC P +5.5V,
and +0.9V P VL P VCC. When power is supplied to VL
while VCC is less than VL, the device automatically
disables logic-level translation function. Also, the device
enters shutdown mode when TS = GND.
High-Speed Operation
The device meets the requirements of high-speed I2C
and MDIO open-drain operation. The maximum data rate
is at least 4MHz for open-drain operation with the total
bus capacitance equal to or less than 100pF.

Three-State Input TS
The device features a three-state input that can put the
device into high-impedance mode. When TS is low,
IOVCC_ and IOVL_ are all high impedance and the internal pullup resistors are disconnected. When TS is high,
the internal pullup resistors are connected when the
corresponding power is in regulation, and the resistors
are disconnected at the side that has no power on. In
many portable applications, one supply is turned off but
the other side is still operating and requires the pullup
resistors to be present. This feature eliminates the need
for external pullup resistors. The level translation function
is off until both power supplies are in range.
Thermal-Shutdown Protection
The device features thermal-shutdown protection to
protect the part from overheating. The device enters
thermal shutdown when the junction temperature exceeds
+150NC (typ), and the device is back to normal operation
again after the temperature drops by approximately 10NC
(typ). When the device is in thermal shutdown, the level
translator is disabled.

Applications Information
Layout Recommendations
Use standard high-speed layout practices when
laying out a board with the MAX14591. For example, to
minimize line coupling, place all other signal lines not connected to the device at least 1x the substrate height of the
PCB away from the input and output lines of the device.
Extended ESD
ESD protection structures are incorporated on all pins to
protect against electrostatic discharges up to ±2kV (HBM)
encountered during handling and assembly. After an ESD
event, the device continues to function without latchup.

ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
setup, test methodology, and test results.
Human Body Model
Figure 5 shows the Human Body Model. Figure 6 shows
the current waveform it generates when discharged
into a low impedance. This model consists of a 100pF
capacitor charged to the ESD voltage of interest that is
then discharged into the device through a 1.5kI resistor.
