Overview
The MAX3181EEUK+T is a single RS-232 receiver in a SOT23-5 package designed for space-constrained applications. It operates from a +3.0V to +5.5V supply with a typical supply current of 0.5µA. The device guarantees true RS-232 performance up to a data rate of 1.5Mbps. It features an INVALID output that indicates valid RS-232 signals at the receiver input, supporting automatic system wake-up functions. The receiver provides a standard inverting output and includes enhanced ESD protection on the RIN input.
Feature Summary
- INVALID output indicates valid RS-232 signal presence
- Standard inverting receiver output
- Enhanced electrostatic discharge protection on inputs
Applications
- Diagnostic Ports
- Telecommunications
- Networking Equipment
- Set-Top Boxes
- Hand-Held Equipment
Procurement Notes
Verify the component against official Analog Devices/Maxim Integrated datasheets to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required tape-and-reel packaging format. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a low-power, single-channel RS-232 receiver with signal validity detection is required. The MAX3181E variant is specifically chosen over the MAX3180E or MAX3182E due to its INVALID output feature, which facilitates automatic system wake-up capabilities. Ensure the application requires a standard inverting output configuration compatible with CMOS logic levels.
Part Context
The MAX3181EEUK+T belongs to the MAX3180E–MAX3183E family of single RS-232 receivers. These devices are engineered for minimal power consumption and small footprint requirements. The family shares common characteristics such as ±15kV ESD protection and operation within the +3V to +5.5V voltage range, differing primarily in output logic and control features.
Replacement Considerations
The MAX3180EEUK+T serves as a functional substitute if the enable (EN) pin is not utilized and the INVALID output is unnecessary. The MAX3182EEUK+T is suitable only if a noninverting output is acceptable. Verify that the replacement maintains the same SOT23-5 package and electrical parameters.
