MAX3182EUK+T

19-1444; Rev 1; 7/99 +3V to +5.5V, 1.5Mbps RS-232 Receivers in SOT23-5 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 performance 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 output that indicates valid RS-232 signals at the receiver input for applications requiring automatic system wakeup. The MAX3180/MAX3181 receivers have a standard inverting output, while the MAX3182/MAX3183 receivers have a noninverting output. ♦ 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 VCC = +3.0V ♦ 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) Ordering Information Applications Diagnostic Ports Set-Top Boxes Telecommunications Digital Cameras Networking Equipment Hand-Held Equipment TEMP.

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. 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 30µs (typ), INVALID goes low. This event typically occurs if the RS232 cable is disconnected or if the connected peripheral 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 0.1µF VCC bypass capacitor is adequate for power-supply decoupling. Connect the bypass capacitor as close to the IC as possible. 5V RIN 50% 50% 0 t PLH VOH ROUT VOL 50% t PHL 50% Chip Information TRANSISTOR COUNT: 41 Figure 1.
