is the parasitic capacitance of the traces, V
is the supply voltage of the driven side (i.e., V

20Mbps OD-to-CMOS Unidirectional Translators
(MAX13004E/MAX13005E)
The MAX13004E/MAX13005E architecture is virtually the
same as that for the bidirectional CMOS-to-CMOS trans-
lators, the only difference being that the output inverter
(inverter 4) at the driving side accommodates the driving
capabilities of an open-drain output (Figure 6).
For proper operation, a pullup resistor needs to be con-
nected from the open-drain output to the power supply of
the driving side. Use pullup resistors no larger than 15kΩ.
230kbps CMOS-to-CMOS Bidirectional Translator
(MAX13000E)
The architecture of the MAX13000E lacks the one-shot
accelerator output stages since the transitions that this
device handles are limited by its data rate, 230kbps
(Figure 7).
For proper operation, the driver must meet the following
conditions: 1kΩ maximum output impedance and 1mA
minimum output current.
230kbps OD-to-CMOS Unidirectional Translators
(MAX13001E/MAX13002E)
The architecture of the MAX13001E/MAX13002E is simi-
lar to that of the 230kbps CMOS-to-CMOS part, with the
difference that it accommodates the driving capability of
an open-drain output on the driving side, and also that it
has only a single one-shot output stage (Figure 8).
For proper operation, a pullup resistor needs to be con-
nected from the open-drain output to the power supply of
the driving side. Use pullup resistors no larger than 15kΩ.
Figure 9 shows a graph of the typical input current ver-
sus input voltage for all of the above configurations.
Enable Output Mode (EN)
The MAX13000E–MAX13005E feature an enable (EN)
input. Drive EN low to set the MAX13000E–MAX13005E
I/Os in tri-state mode. Drive EN high (V
L
) for normal
operation.
±15kV ESD Protection
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/OV
CC
lines have extra protection
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
