MAX3183EEUK-T

Overview

The MAX3183EEUK-T is a single RS-232 receiver in a SOT23-5 package designed for space-constrained applications. It operates on a +3.0V to +5.5V supply with a typical supply current of 0.5µA and guarantees data rates up to 1.5Mbps. The device features an INVALID output that indicates valid RS-232 signals at the receiver input, supporting automatic system wake-up functions. It provides a noninverting ROUT output and includes enhanced ESD protection rated at ±15kV (Human Body Model) and ±8kV (IEC 1000-4-2 Contact Discharge). The component meets EIA/TIA-232 and V.28/V.24 specifications down to VCC = +3.0V.

Feature Summary

• INVALID output indicates valid RS-232 signal presence at the receiver input
• Noninverting RS-232 output configuration
• Enhanced electrostatic discharge protection on receiver inputs

Applications

• Diagnostic Ports
• Telecommunications
• Networking Equipment
• Set-Top Boxes
• Hand-Held Equipment

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging requirements. Ensure the ordering code matches the exact temperature range and package variant required for the design. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a noninverting RS-232 receiver with an invalid-signal indicator is required. It is suitable for designs needing minimal power consumption and high ESD immunity within a compact footprint. Verify compatibility with the host logic voltage levels and ensure the application does not require an enable control input, as this variant lacks that feature.

Part Context

This part belongs to the MAX3180E–MAX3183E family of single RS-232 receivers. It shares the same SOT23-5 package and core electrical performance as its siblings but differs in output logic and control features. Specifically, it pairs the noninverting output of the MAX3182E with the INVALID detector of the MAX3181E.

Replacement Considerations

The MAX3181EEUK-T serves as a functional substitute if an inverting output is acceptable. The MAX3182EEUK-T is an alternative if an enable input is needed instead of the INVALID detector. All variants share identical packages and basic electrical ratings.

FAQ

What is the function of the INVALID output?

The INVALID output goes low if no valid RS-232 signal levels appear on the RIN input for approximately 30µs, indicating conditions such as a disconnected cable or powered-off peripheral.

Does the MAX3183EEUK-T have an enable input?

No, the MAX3183EEUK-T does not feature an EN input; it operates continuously without a shutdown or high-impedance control state.

Is the receiver output inverting or noninverting?

The MAX3183EEUK-T provides a noninverting receiver output relative to the input signal.
