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.

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.
