1.62V to 3.6V Improved High-Speed LLT
General Description
The MAX13042E–MAX13045E 4-channel, bidirectional
level translators provide the level shifting necessary for
100Mbps data transfer in multivoltage systems. The
MAX13042E–MAX13045E are ideally suited for level
translation in systems with four channels. Externally
applied voltages, V
CC
and V
L
, set the logic levels on
either side of the device. Logic signals present on the
V
L
side of the device appear as a high-voltage logic
signal on the V
CC
side of the device and vice-versa.
The MAX13042E–MAX13045E operate at full speed
with external drivers that source as little as 4mA output
current or larger. Each input/output (I/O) channel is
pulled up to V
CC
or V
L
by an internal 30µA current
source, allowing the MAX13042E–MAX13045E to be
driven by either push-pull or open-drain drivers.
The MAX13042E–MAX13045E feature an enable (EN)
input that places the devices into a low-power shutdown
mode when driven low. The MAX13042E–MAX13045E
feature an automatic shutdown mode that disables the
part when V
CC
is less than V
L
. The state of I/O V
CC_
and
I/O V
L_
during shutdown is chosen by selecting the
appropriate part version. (See the
Ordering Information/
Selector Guide).
The MAX13042E–MAX13045E operate with V
CC
volt-
ages from +2.2V to +3.6V and V
L
voltages from +1.62V
to +3.2V, making them ideal for data transfer between
low-voltage ASIC/PLDs and higher voltage systems.
The MAX13042E–MAX13045E are available in 12-bump
UCSP™ (1.54mm x 2.12mm) and 14-pin TDFN (3mm x
3mm) packages, and operate over the extended -40°C
to +85°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
All units are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed by
correlation and design and not production tested.
Note 2:
V
L
must be less than or equal to V
CC
during normal operation. However, V
L
can be greater than V
CC
during startup and
shutdown conditions.
Note 3:
When V

is below V
L
by more than the V

shutdown threshold, the device turns off its pullup generators and the I/Os
enter their respective shutdown states.
Note 4:
Guaranteed by design.

Input thresholds are referenced to the boost circuit.
