【15kV ESD-Protected, 460kbps, 1レA, RS-232-Compatible Transceiver
General Description
The MAX3314E is a ±5V-powered EIA/TIA-232-compat-
ible interface. It has one transmitter and one receiver in
a flow-through architecture. The transmitter output and
the receiver input are protected to ±15kV using IEC
1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2
Contact Discharge, and ±15kV using the Human Body
Model.
The transmitter has a low-dropout output stage provid-
ing minimum RS-232-compatible ±3.7V output levels
while driving 3kΩand 1000pF at 460kbps. Both +5V
and -5V must be supplied externally.
The MAX3314E has a SHDNfunction that reduces sup-
ply current to 1µA. The transmitter is disabled and put
into tristate while the receiver remains active.
The MAX3314E is available in 8-pin µMAX, SOT23, and
SO packages.

Detailed Description
RS-232-Compatible Drivers
The transmitter is an inverting level translator that con-
verts CMOS-logic levels to ±3.7V EIA/TIA-232-compati-
ble levels. It guarantees data rates up to 460kbps with
worst-case loads of 3kΩin parallel with 1000pF. When
SHDNis driven low, the transmitter is disabled and put
into tristate. The transmitter input does not have a pull-
up resistor. Connect to ground if unused.
RS-232-Compatible Receivers
The MAX3314E’s receiver converts RS-232 signals to
CMOS-logic output levels. The receiver is rated to
receive signals to ±25V. It will remain active during
shutdown mode.
MAX3314E Shutdown Mode
In shutdown mode, the transmitter output is put into high
impedance (Table 1). This reduces supply current to 1µA.
The time required to exit shutdown is less than 2.5µs.
Applications Information
Capacitor Selection
The capacitor type used is not critical for proper opera-
tion; either polarized or nonpolarized capacitors are
acceptable. If polarized capacitors are used, connect
polarity as shown in the Typical Operating Circuit.
Bypass VCCand V- to ground with at least 0.1µF.
Transmitter Outputs When
Exiting Shutdown
Figure 1 shows the transmitter output when exiting
shutdown mode. The transmitter is loaded with 3kΩin
parallel with 1000pF. The transmitter output displays no
ringing or undesirable transients as the MAX3314E
comes out of shutdown.
High Data Rates
The MAX3314E maintains minimum RS-232-compatible
±3.7V transmitter output voltage even at high data rates.
Figure 2 shows a transmitter loopback test circuit.
Figure 3 shows the loopback test result at 120kbps, and
Figure 4 shows the same test at 250kbps.
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.
The MAX3314E driver outputs and receiver inputs have
extra protection against static discharge. Maxim’s engi-
neers have developed state-of-the-art structures to pro-
tect these pins against ESD of ±15kV without damage.
The ESD structures withstand high ESD in all states: nor-
mal operation, shutdown, and powered down. After an
ESD event, Maxim’s E versions keep working without
latchup, whereas competing products can latch and
must be powered down to remove latchup.
ESD protection can be tested in various ways. The trans-
mitter outputs and receiver inputs of the product family
are characterized for protection to the following limits:±15kV using the Human Body Model±8kV using the Contact Discharge method specified
in IEC 1000-4-2±15kV using the IEC 1000-4-2 Air-Gap method
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 5 shows the Human Body Model, and Figure 6
shows the current waveform it generates when dis-
charged into 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
1.5kΩresistor.

MAX3314E
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and per-
formance of finished equipment; it does not specifically
refer to ICs. The MAX3314E helps design equipment
that meets Level 4 (the highest level) of IEC 1000-4-2
without the need for additional ESD-protection compo-
nents.
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 7 shows the IEC 1000-4-2 model, and Figure 8
shows the current waveform for the 8kV, IEC 1000-4-2,
Level 4, ESD Contact Discharge test.
The Air-Gap test involves approaching the device with a
charged probe. The Contact Discharge method connects
the probe to the device before the probe is energized.
Machine Model
The Machine Model for ESD tests all pins using a
200pF storage capacitor and zero discharge resis-
tance. Its objective is to emulate the stress caused by
contact that occurs with handling and assembly during
manufacturing. Of course, all pins require this protec-
tion during manufacturing, not just RS-232 inputs and
outputs. Therefore, after PC board assembly, the
Machine Model is less relevant to I/O ports.
