+3V to +5.5V, 1.5Mbps
RS-232 Receivers in SOT23-5
0–MAX183
General Description
Features
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.
♦ Tiny SOT23-5 Package
♦ 0.5µA Supply Current
♦ 1.5Mbps Guaranteed Data Rate
♦ Meet EIA/TIA-232 and V.28/V.24 Specifications
Down to V = +3.0V
CC
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.
♦ INVALID Output Indicates Valid RS-232 Signal at
Receiver Input (MAX3181/MAX3183)
♦ Three-State TTL/CMOS Receiver Output
(MAX3180/MAX3182)
♦ Noninverting RS-232 Output (MAX3182/MAX3183)
