MAX200–MAX209/MAX211/MAX213
RS-232 Receivers
The receivers convert RS-232 signals to CMOS logic
output levels. Receiver outputs are inverting, maintain-
ing compatibility with driver outputs. The guaranteed
receiver input thresholds of +0.8V and +2.4V are signifi-
cantly tighter than the Q3.0V threshold required by the
EIA/TIA-232E specification. This allows receiver inputs
to respond to TTL/CMOS logic levels and improves noise
margin for RS-232 levels.
The MAX200–MAX209/MAX211/MAX213 guaranteed
+0.8V threshold (+0.6V in shutdown for the MAX213)
ensures that receivers shorted to ground have a logic 1
output. Also, the 5kI input resistance to ground ensures
that a receiver with its input left open also has a logic 1
output.
Receiver inputs have approximately +0.5V hysteresis.
This provides clean output transitions, even with slow
rise and fall time input signals with moderate amounts of
noise and ringing. In shutdown, the MAX213 receivers
R4 and R5 have no hysteresis.
