MAX3013
+1.2V to +3.6V, 0.1A, 100Mbps,
8-Channel Level Translators
______________________________________________________________________________________

Detailed Description
The MAX3013 logic-level translator provides the level
shifting necessary to allow 100Mbps data transfer in a
multivoltage system. 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 higher voltage logic signal on the VCC side
of the device, and vice-versa. The MAX3013 bidirection-
al level translator allows data translation in either direc-
tion (VL
VCC) on any single data line. The MAX3013
accepts VL from +1.2V to (VCC - 0.4V) and operate with
VCC from +1.65V to +3.6V, making it ideal for data trans-
fer between low-voltage ASICs/PLDs and higher voltage
systems.
The MAX3013 features an input enable mode (EN) that
reduces VCC and VL supply currents to 0.1A, when in
tristate mode. This device operates at a guaranteed
data rate of 100Mbps for VL > +1.8V.
Level Translation
For proper operation, ensure that +1.65V
≤ VCC ≤ +3.6V,
+1.2V
≤ VL ≤ (VCC - 0.4V). During power-up sequencing,
VL
≥ VCC does not damage the device. During power-
supply sequencing, when VCC is floating and VL is pow-
ering up, up to 40mA current can be sourced to each
load on the VL 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 VL or 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: <25
Ω 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
25k
Ω. 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.
