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 voltages, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side of
the device appear as a higher voltage logic signal on
the VCC side of the device and vice versa. The
MAX13035E features a CLK_RET output that returns the
same clock signal applied to the CLK_VL 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 VCC or VL 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 VCC is less than VL. The state of I/O VCC_ and I/O VL_ during shutdown is chosen by selecting the appropriate part version (see Ordering Information/Selector Guide located within the full datasheet).
The MAX13030E–MAX13035E accept VCC voltages
from +2.2V to +3.6V and VL 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.
