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
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 high-voltage logic
signal on the VCC side of the device and vice-versa.
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
pulled up to VCC or VL by an internal 30µA current
source, allowing the MAX13042E–MAX13045E to be
driven by either push-pull or open-drain drivers.
o Compatible with 4mA Input Drivers or Larger
o 100Mbps Guaranteed Data Rate
o Four Bidirectional Channels
o Enable Input
o ±15kV ESD Protection on I/O VCC_ Lines
o +1.62V VL +3.2V and +2.2V VCC +3.6V
Supply Voltage Range
o 12-Bump UCSP (1.54mm x 2.12mm) and
14-Pin TDFN (3mm x 3mm) Lead-Free Packages
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
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 the Ordering Information/
Selectorwww.DataSheet4U.com Guide).
The MAX13042E–MAX13045E operate with VCC volt-
ages 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 MAX13042E–MAX13045E are available in 12-bump
UCSP™ (1.54mm x 2.12mm) and 14-pin TDFN (3mm x
3mm) packages, and operate over the extended -40°C
to +85°C temperature range.
