MAX3180-MAX3183 Datasheet, PDF (1/6 Pages) Maxim Integrated Products – +3V to +5.5V, 1.5Mbps RS-232 Receivers in SOT23-5

19-1444; Rev 1; 7/99
+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 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.
