MAX3181EEUK-T
【15kV ESD-Protected, 0.5レA, +3V to +5.5V, 1.5Mbps RS-232 Receivers in SOT23-5
General Description
The MAX3180E–MAX3183E single RS-232 receivers in
a SOT23-5 package are designed for space- and cost-
constrained applications requiring minimal RS-232
communications. The receiver inputs are protected to
±15kV using IEC 1000-4-2 Air-Gap Discharge, to ±8kV
using IEC 1000-4-2 Contact Discharge, and to ±15kV
per the Human Body Model, ensuring compliance with
international standards.
The devices minimize power and heat dissipation by
consuming only 0.5µA supply current from a +3.0V to
+5.5V supply, and they guarantee true RS-232 perfor-
mance up to a 1.5Mbps data rate. The MAX3180E/
MAX3182E feature a three-state TTL/CMOS receiver
output that is controlled by an ENlogic input. The
MAX3181E/MAX3183E feature an INVALIDoutput that
indicates valid RS-232 signals at the receiver input for
applications requiring automatic system wake-up. The
MAX3182E/MAX3183E have a noninverting output,
while the MAX3180E/MAX3181E have a standard
inverting output.

Detailed Description
The MAX3180E–MAX3183E are EIA/TIA-232 and V.28/
V.24communications receivers that convert RS-232
signals to CMOS logic levels. They operate on a +3V to
+5.5V supply, have 1.5Mbps data rate capability, and
feature enhanced electrostatic discharge (ESD) protec-
tion (see ESD Protection). All of these devices achieve
a typical supply current of 0.5µA. The MAX3180E/
MAX3182E have a receiver enable control (EN). The
MAX3181E/MAX3183E contain a signal invalid output
(INVALID). The MAX3180E/MAX3181E invert the ROUT
signal relative to RIN (standard RS-232). The
MAX3182E/MAX3183E outputs are not inverted. The
devices come in tiny SOT23-5 packages.

Pin Description
Signal Invalid Detector
If no valid signal levels appear on RIN for 30µs (typ),INVALIDgoes low. This event typically occurs if the
RS-232 cable is disconnected, or if the connected
peripheral transmitter is turned off. INVALIDgoes high
when a valid level is applied to the RS-232 receiver
input. Figure 2 shows the input levels and timing dia-
gram for INVALIDoperation.
Enable Input

The MAX3180E/MAX3182E feature an enable input
(EN). Drive ENhigh to force ROUT into a high-imped-
ance state. In this state, the devices ignore incoming
RS-232 signals. Pull ENlow for normal operation.
ESD Protection

As with all Maxim devices, ESD protection structures
are incorporated on all pins to protect against ESD
encountered during handling and assembly. The
receiver inputs of the MAX3180E–MAX3183Ehave extra
protection against static electricity. Maxim’s engineers
have developed state-of-the-art structures enabling
these pins to withstand ESD up to ±15kV without dam-
age or latchup. The receiver inputs of the MAX3180E–
MAX3183Eare characterized for protection to the fol-
lowing limits:±15kV using the Human Body Model±8kV using the Contact Discharge method specified
in IEC 1000-4-2±15kV using the Air-Gap Discharge method speci-
fied in IEC 1000-4-2
Human Body Model

Figure 3 shows the Human Body Model, and Figure 4
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 inter-
est, and then discharged into the test device through a
1.5kΩresistor.

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 MAX3180E–MAX3183Eenable the
design of equipment that meets the highest level (Level
4) 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, the ESD withstand
voltage measured to this standard is generally lower
than that measured using the Human Body. Figure 5
shows the IEC 1000-4-2 model, and Figure 6 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 con-
nects the probe to the device before the probe is ener-
gized.
Power-Supply Decoupling

In most circumstances, a 0.1µF VCCbypass capacitor
is adequate. Connect the bypass capacitor as close to
the IC as possible.
