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 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.

IEC 1000-4-2 The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to ICs. The MAX3180E–MAX3183E enable the design of equipment that meets the highest level (Level 4) of IEC 1000-4-2 without the need for additional ESDprotection 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.
