Detailed Description

The MAX3013 logic-level translator provides the level

shifting necessary to allow 100Mbps data transfer in a

of the device, and vice-versa. The MAX3013 bidirection-

al level translator allows data translation in either direc-

fer between low-voltage ASICs/PLDs and higher voltage

systems.

The MAX3013 features an input enable mode (EN) that

tristate mode. This device operates at a guaranteed

Level Translation

For proper operation, ensure that +1.65V

+1.2V

ering up, up to 40mA current can be sourced to each

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

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.
