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 memory
card level translation, as well as generic level translation
in systems with six channels. Externally applied volt-
ages, V

signal applied to the CLK_V
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
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

the MAX13030E–MAX13035E automatically enters a

The MAX13030E–MAX13035E architecture is based on
an nMOS pass gate and output accelerator stages (see
Figure 6). Output accelerator stages are always in tri-
state mode except when there is a transition on any of
the translators on the input side, either I/O V

active during the one-shot pulse. This can lead to some
current feeding into the external source that is driving the
translator. However, this behavior helps to speed up the
transition on the driven side.
The MAX13030E–MAX13035E have internal current
sources capable of sourcing 30µA to pullup the I/O
lines. These internal pullup current sources allow the
inputs to be driven with open-drain drivers, as well as
push-pull drivers. It is not recommended to use exter-
nal pullup resistors on the I/O lines. The architecture of
the MAX13030E–MAX13035E permit either side to be
driven with a minimum of 4mA drivers or larger.
The MAX13030E–MAX13035E I/O are designed to drive
CMOS inputs. Do not load the I/O lines with a resistive
load less than 25kΩ and do not place an RC circuit at
the input of these devices to slow down the edges. If a
slower rise/fall time is required, refer to the MAX3000E/
MAX3001E logic-level translator datasheet. For I
level translation, refer to the MAX3372E–MAX3379E/
MAX3390E–MAX3393E datasheet.
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
