MAXIM MAX3013 User Manual

General Description

The MAX3013 8-channel level translator provides the
level shifting necessary to allow 100Mbps data transfer
in a multivoltage system. Externally applied voltages,
VCCand VL, set the logic levels on either side of the
device. Logic signals present on the V

L

side of the
device appear as a higher voltage logic signal on the
VCCside of the device, and vice-versa.

The MAX3013 features an EN input that, when at logic
low, places all inputs/outputs on both sides in tristate
and reduces the V

CC

and VL supply currents to 0.1µA.
This device operates at a guaranteed data rate of
100Mbps for VL> 1.8V.

The MAX3013 accepts a V

CC

voltage from +1.65V to
+3.6V and a VLvoltage from +1.2V to (VCC- 0.4V), mak­ing it ideal for data transfer between low-voltage
ASICs/PLDs and higher voltage systems. The MAX3013
is available in 5 x 4 UCSP™, 20-pin 5mm x 5mm QFN,
and 20-pin TSSOP packages.

Detailed Description

The MAX3013 logic-level translator provides the level
shifting necessary to allow 100Mbps data transfer in a
multivoltage system. Externally applied voltages, V

CC

and VL, set the logic levels on either side of the device.
Logic signals present on the V

L

side of the device

appear as a higher voltage logic signal on the V

CC

side
of the device, and vice-versa. The MAX3013 bidirection­al level translator allows data translation in either direc­tion (VL↔ VCC) on any single data line. The MAX3013
accepts V

L

from +1.2V to (VCC- 0.4V) and operate with
VCCfrom +1.65V to +3.6V, making it ideal for data trans­fer between low-voltage ASICs/PLDs and higher voltage
systems.

The MAX3013 features an input enable mode (EN) that
reduces VCCand VLsupply currents to 0.1µA, when in
tristate mode. This device operates at a guaranteed
data rate of 100Mbps for V

L

> +1.8V.

Level Translation

For proper operation, ensure that +1.65V ≤ VCC≤ +3.6V,
+1.2V ≤ V

L

≤ (VCC- 0.4V). During power-up sequencing,
VL≥ VCCdoes not damage the device. During power­supply sequencing, when VCCis floating and VLis pow­ering up, up to 40mA current can be sourced to each
load on the V

L

side, yet the device does not latch up.
The maximum data rate depends heavily on the load
capacitance (see the Typical Operating Characteristics,
Rise/Fall Times), output impedance of the driver, and the
operating voltage range (see the Timing Characteristics).

Input Driver Requirements

The MAX3013 architecture is based on a one-shot
accelerator output stage (see Figure 5). Accelerator
output stages are always in tristate mode except when
there is a transition on any of the translators on the
input side, either I/O VLor I/O VCC. Then, a short pulse
is generated during which the accelerator output
stages become active and charge/discharge the
capacitances at the I/Os. Due to its bidirectional nature,
both input 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 operation, the external driver must meet the
following conditions: <25Ω output impedance and
>20mA output current. Figure 6 shows a graph of
Typical Input Current vs. Input Voltage.

Output Load Requirements

The MAX3013 I/O was designed to drive CMOS inputs.
Do not load the I/O lines with a resistive load less than
25kΩ. Also, do not place an RC circuit at the input of
the MAX3013 to slow down the edges. If a slower data
rate is required, please see the MAX3000E/MAX3001E
logic-level translator.

For I2C level translation, please refer to the MAX3372E–
MAX3379E/MAX3390E–MAX3393E data sheet.

Enable Input (EN)

The MAX3013 features an EN input. Pull EN low to set
the MAX3013 I/O on both sides in tristate output mode.
Drive EN to logic high (VL) for normal operation.

Applications Information

Power-Supply Decoupling

To reduce ripple and the chance of introducing data
errors, bypass V

L

and VCCto ground with a 0.1µF
ceramic capacitor. Place the bypass capacitors as
close to the power-supply input pins as possible.

8-Bit Bus Translation

The MAX3013 level-shifts the data present on the I/O
line between +1.2V to +3.6V, making it ideal for level
translation between a low-voltage ASIC and a higher
voltage system. The Typical Operating Circuit shows
the MAX3013 bidirectional translator in an 8-bit bus
level translation from a 1.8V system to a 3.3V system
and vice versa.

Unidirectional vs. Bidirectional Level

Translator

The MAX3013 bidirectional translator can operate as a
unidirectional device to translate signals without inver­sion. This device provides the smallest solution (UCSP
package) for unidirectional level translation without inver­sion.
