In shutdown mode, the receiver outputs are high imped-

Logic Supply Input
Unlike other RS-232 interface devices where the receiver
outputs swing between 0 and V
CC
, the MAX3388E/
MAX3389E feature a separate logic supply input (V

)
that sets V
OH
for the receiver outputs and sets thresh-
olds for the transmitter inputs. This feature allows a
great deal of flexibility in interfacing to many different
types of systems with different logic levels. Connect
this input to the host logic supply (1.8V

±15kV ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against ESDs encoun-
tered during handling and assembly. The MAX3388E/
MAX3389E
’
s driver outputs, receiver inputs, the hand-
shaking input LIN, and the switch terminal SWIN have
extra protection against static electricity. Maxim has
developed state-of-the-art structures to protect these pins
against an ESD of ±15kV without damage. The ESD
structures withstand high ESD in all states: normal opera-
tion, shutdown, and powered down. After an ESD event,

version devices keep working without
latchup, whereas competing RS-232 products can latch
and must be powered down to remove latchup. ESD pro-
tection can be tested in various ways. The transmitter out-
puts and receiver inputs of this product family are
characterized for protection to the following limits:
1) ±15kV using the Human Body Model
2) ±8kV using the Contact Discharge method specified
in IEC 1000-4-2
3) ±15kV using IEC 1000-4-2

ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
Human Body Model
Figure 3a shows the Human Body Model, and Figure 3b
shows the current waveform it generates when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of interest,
which is then discharged into the test device through a
1.5k
resistor.
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not specifi-
cally refer to ICs. The MAX3388E/MAX3389E helps you
design equipment that meets Level 4 (the highest level)
of IEC 1000-4-2, without the need for additional ESD-
protection components.
The major difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2, because series resistance is
lower in the IEC 1000-4-2 model. Hence, the ESD with-
stand voltage measured to IEC 1000-4-2 is generally
lower than that measured using the Human Body
Model. Figure 4a shows the IEC 1000-4-2 model, and
Figure 4b shows the current waveform for the ±8kV IEC
1000-4-2 Level 4 ESD Contact Discharge test.
