±15kV ESD-Protected, 0.5µA, +3V to +5.5V,
1.5Mbps RS-232 Receivers in SOT23-5
0–MAX183E
General Description
Features
The MAX3180E–MAX3183E single RS-232 receivers in
a SOT23-5 package are designed for space- and cost-
constrained applications requiring minimal RS-232
communications. The receiver inputs are protected to
±15kV using IEC 1000-4-2 Air-Gap Discharge, to ±8kV
using IEC 1000-4-2 Contact Discharge, and to ±15kV
per the Human Body Model, ensuring compliance with
international standards.
♦ Tiny SOT23-5 Package
♦ ESD-Protected RS-232 Input
±15kV—Human Body Model
±8kV—IEC 1000-4-2, Contact Discharge
±15kV—IEC 1000-4-2, Air-Gap Discharge
♦ 0.5µA Supply Current
♦ 1.5Mbps Guaranteed Data Rate
The devices minimize power and heat dissipation by
consuming only 0.5µA supply current from a +3.0V to
+5.5V supply, and they guarantee true RS-232 perfor-
mance up to a 1.5Mbps data rate. The MAX3180E/
MAX3182E feature a three-state TTL/CMOS receiver
output that is controlled by an EN logic input. The
MAX3181E/MAX3183E feature an INVALID output that
indicates valid RS-232 signals at the receiver input for
applications requiring automatic system wake-up. The
MAX3182E/MAX3183E have a noninverting output,
while the MAX3180E/MAX3181E have a standard
inverting output.
