Single-/Dual-/Quad-Level Translators
The MAX13013/MAX13014/MAX3023 logic-level trans-
lators provide the level shifting necessary to allow
100Mbps data transfer in a multivoltage system.

+3.6V, making them ideal for data transfer between
low-voltage ASICs/PLDs and higher voltage systems.
When in tri-state mode, the MAX13013/MAX13014/
MAX3023 reduce the V

the load capacitance (see the Typical Operating
Characteristics Rise/Fall Time graph), output impedance
of the driver, and the operating voltage range (Table 1).
The MAX13013/MAX13014/MAX3023 architecture is
based on a one-shot accelerator output stage (see
Figure 5). Accelerator output stages are in tri-state
mode except when there is a transition on any of the
translators on the input side, either I/O V
A short pulse is then generated during which the accel-
erator output stages become active and charge/dis-
charge the capacitances at the I/Os. Due to the
architecture, both sides 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 simply helps to speed up the
transition on the driven side.
For proper operation, the driver has to meet the follow-
ing conditions: less than 25Ω output impedance and
greater than 20mA peak output current capability.
