Rainbow Electronics MAX13045E - Manual

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.
