General Description

The MAX3180¨CMAX3183 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 0.5?A supply current from a +3.0V to +5.5V supply voltage. They guarantee true RS-232 per formance 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 out put that indicates valid RS-232 signals at the receiver input for applications requiring automatic system wake up. The MAX3180/MAX3181 receivers have a standard inverting output, while the MAX3182/MAX3183 receivers have a noninverting output.
