General Description
The MAX3180E–MAX3183E single RS-232 receivers in
a SOT23-5 package are designed for space- and costconstrained 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 performance up to a 1.5Mbps data rate. The MAX3180E/
MAX3182E feature a three-state TTL/CMOS receiver
output that is controlled by an EN logic input. The
MAX3181E/MAX3183E feature an INVALID output 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
