The MAX3000E/MAX3001E/MAX3002–MAX3012 logic-
level translators provide the level shifting necessary to
allow data transfer in a multivoltage system. Externally

The MAX3000E/MAX3001E/MAX3002/MAX3003 are
bidirectional level translators allowing data translation in
either direction (V
These devices use an architecture specifically
designed to be bidirectional without the use of a direc-
tion pin. The MAX3004–MAX3012 unidirectional level
translators level shift data in one direction (V
V
MAX3000E/MAX3001E/ MAX3002–MAX3012 accept V
from +1.2V to +5.5V. All devices have V
from +1.65V to +5.5V, making them ideal for data trans-
fer between low-voltage ASICs/PLDs and higher volt-
age systems.
The MAX3000E/MAX3001E/MAX3002/MAX3004–
MAX3012 feature an output enable mode that reduces
V
current to less than 2µA when in shutdown. The
MAX3000E/MAX3001E have ±15kV ESD protection on
the V
route signals externally. The MAX3000E operates at a
guaranteed data rate of 230kbps; the MAX3001E oper-
ates at a guaranteed data rate of 4Mbps and the
MAX3002–MAX3012 are guaranteed with a data rate of
20Mbps of operation over the entire specified operating
voltage range.
For proper operation, ensure that +1.65V ≤ V

The maximum data rate also depends heavily on the
load capacitance (see the Typical Operating
Characteristics ), output impedance of the driver, and
the operational voltage range (see the Timing
Characteristics table).
The MAX3001E/MAX3002–MAX3012 architecture is
based on a one-shot accelerator output stage. See

state except when there is a transition on any of the
translators on the input side, either I/O V
When there is such a transition, the accelerator stages
become active, charging (discharging) the capacitances
at the I/Os. Due to its bidirectional nature, both stages
become 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.
For proper full-speed operation, the output current
of a device that drives the inputs of the MAX3000E/
MAX3001E/MAX3002–MAX3012 should meet the fol-
lowing requirements:
• MAX3000E (230kbps):
• MAX3001E (4Mbps):
• MAX3002–MAX3012 (20Mbps):

voltage (i.e., V

The MAX3000E/MAX3001E/MAX3002 and the MAX3004–
MAX3012 feature an EN input, and the MAX3003 has an
EN A/B input. Pull EN low to set the MAX3000E/

MAX3003 is intended for bus multiplexing or bus switch-

As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against electro-
static discharges encountered during handling and
assembly. The I/O V
against static discharge. Maxim’s engineers have
developed state-of-the-art structures to protect these
pins against ESD of ±15kV without damage. The ESD
structures withstand high ESD in all states: normal
operation, three-state output mode, and powered
down. After an ESD event, Maxim’s E versions keep
working without latchup, whereas competing products
can latch and must be powered down to remove
latchup.
