Detailed Description
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 0.5A 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.
Signal Invalid Detector
If no valid signal levels appear on RIN for 30s (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.
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 0.1F VCC bypass capacitor
is adequate for power-supply decoupling. Connect the
bypass capacitor as close to the IC as possible.
