±15kV ESD-Protected, 0.5µA, +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 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. o Tiny SOT23-5 Package o ESD-Protected RS-232 Input ±15kV—Human Body Model ±8kV—IEC 1000-4-2, Contact Discharge ±15kV—IEC 1000-4-2, Air-Gap Discharge o 0.5µA Supply Current o 1.5Mbps Guaranteed Data Rate o Meets EIA/TIA-232 and V.28/V.24 Specifications Down to VCC = +3.0V o INVALID Output Indicates Valid RS-232 Signal at Receiver Input (MAX3181E/MAX3183E) o Three-State TTL/CMOS Receiver Output (MAX3180E/MAX3182E) o Noninverting RS-232 Output (MAX3182E/MAX3183E)

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.
