General Description

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.

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.

+3V to +5.5V, 1.5Mbps RS-232 Receivers in SOT23-5 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 supply current. The MAX3180/MAX3182 have a receiver enable control (EN), while the MAX3181/MAX3183 contain a signal invalid output (INVALID). The MAX3180/ MAX3181 invert the ROUT signal relative to RIN.
