+3V to +5.5V, 1.5Mbps RS-232 Receivers in SOT23-5
General Description
The MAX3180–MAX3183 are single RS-232 receivers in a SOT23-5 package for space- and cost-constrained applications requiring minimal RS-232 communications. These devices minimize power and heat dissipation by consuming only 0.5µA supply current from a +3.0V to +5.5V supply voltage. They guarantee true RS-232 performance up to a 1.5Mbps data rate. The MAX3180/MAX3182 feature a three-state TTL/ CMOS receiver output that is controlled by an EN logic input. The MAX3181/MAX3183 feature an INVALID output that indicates valid RS-232 signals at the receiver input for applications requiring automatic system wakeup. The MAX3180/MAX3181 receivers have a standard inverting output, while the MAX3182/MAX3183 receivers have a noninverting output. o Tiny SOT23-5 Package o 0.5µA Supply Current o 1.5Mbps Guaranteed Data Rate o Meet 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 (MAX3181/MAX3183) o Three-State TTL/CMOS Receiver Output (MAX3180/MAX3182) o Noninverting RS-232 Output (MAX3182/MAX3183)

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.
