General Description
The MAX13030E–MAX13035E 6-channel, bidirectional
level translators provide the level shifting necessary for
100Mbps data transfer in multivoltage systems. The
MAX13030E–MAX13035E are ideally suited for memo-
ry-card level translation, as well as generic level trans-
lation in systems with six 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 higher voltage logic signal on
the V
CC
side of the device and vice versa. The
MAX13035E features a CLK_RET output that returns the
same clock signal applied to the CLK_V
L
input.
The MAX13030E–MAX13035E operate at full speed
with external drivers that source as little as 4mA output
current. Each I/O channel is pulled up to V
CC
or V
L
by
an internal 30µA current source, allowing the
MAX13030E–MAX13035E to be driven by either push-
pull or open-drain drivers.
The MAX13030E–MAX13034E feature an enable (EN)
input that places the device into a low-power shutdown
mode when driven low. The MAX13030E–MAX13035E
features 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
Ordering Information/
Selector Guide
).
The MAX13030E–MAX13035E accept V
CC
voltages
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 MAX13030E–MAX13035E are available in 16-bump
UCSP (2mm x 2mm) and 16-pin TQFN (4mm x 4mm)
packages, and operate over the extended -40°C to
+85°C temperature range.
