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)

Signal Invalid Detector
Detailed Description
If no valid signal levels appear on RIN for 30µs (typ),
INVALID goes low. This event typically occurs if the RS-
232 cable is disconnected or if the connected peripher-
al transmitter is turned off. INVALID goes high when a
valid level is applied to the RS-232 receiver input.
Figure 2 shows the input levels and timing diagram for
INVALID operation.
The MAX3180–MAX3183 are EIA/TIA-232 and V.28/
V.24 communications receivers that convert RS-232
signals to CMOS logic levels. The devices operate on a
supply voltage of +3V to +5.5V and have a 1.5Mbps
data rate capability. They achieve a 0.5µA typical sup-
ply current. The MAX3180/MAX3182 have a receiver
enable control (EN), while the MAX3181/MAX3183 con-
tain a signal invalid output (INVALID). The MAX3180/
MAX3181 invert the ROUT signal relative to RIN. The
MAX3182/MAX3183 are not inverted. The devices
come in SOT23-5 packages.
Enable Input
The MAX3180/MAX3182 feature an enable input. Drive
EN high to force ROUT into a high-impedance state. In
this state, the devices ignore incoming RS-232 signals.
Drive EN low for normal operation.
Power-Supply Decoupling
In most circumstances, a 0.1µF V
bypass capacitor
CC
5V
is adequate for power-supply decoupling. Connect the
RIN
50%
50%
bypass capacitor as close to the IC as possible.
