MAXIM MAX13055E, MAX13058E User Manual

General Description

The MAX13055E–MAX13058E 8-channel, bidirectional
level translators provide the level shifting necessary for
100Mbps data transfer in multivoltage systems. The
MAX13055E–MAX13058E are ideal for level translation
in systems with 8 channels. Externally applied voltages,
V

CC

and VL, set the logic levels on either side of the

device. Logic-high signals presented on the V

L

side of

the device appear as a logic-high signal on the V

CC

side of the device and vice versa.

The MAX13055E–MAX13058E 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 VLby an internal 40µA current
source, allowing the MAX13055E–MAX13058E to be
driven by either push-pull or open-drain drivers.

The MAX13055E–MAX13058E feature an enable (EN)
input to place the device into a low-power shutdown
mode when driven low. In addition, the MAX13055E–
MAX13058E feature an automatic shutdown mode that
disables the part when V

CC

is less than VL. Each

device has a different I/O V

L_

and I/O V

CC_

state during

shutdown mode (see the

Ordering Information/Selector

Guide

).

The MAX13055E–MAX13058E operate with V

CC

voltages
from +2.2V to +3.6V and VLvoltages from +1.62V to
+3.2V, making them ideal for data transfer between low­voltage ASIC/PLDs and higher voltage systems. The
MAX13055E–MAX13058E are available in 0.4mm pitch,
24-bump WLP and 28-pin TQFN (3.5mm x 5.5mm) pack­ages. The MAX13055E–MAX13058E operate over the
extended -40°C to +85°C temperature range.

ABSOLUTE MAXIMUM RATINGS

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.
