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

the device appear as a higher voltage logic signal on

MAX13035E features a CLK_RET output that returns the

The MAX13030E–MAX13035E operate at full speed

with external drivers that source as little as 4mA output

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

appropriate part version (see

Ordering Information/

Selector Guide).

+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.
