1.62V to 3.6V Improved High-Speed LLT
General Description
Features
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

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

Typical Operating Circuit
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
