MAX202ECSE

Drivers, Receivers, Transceivers Overview

The MAX202ECSE is a full-duplex RS-232 transceiver featuring two drivers and two receivers in a 16-pin narrow SO package. It operates from a single +4.5V to +5.5V supply using an integrated charge pump, eliminating the need for external bipolar supplies. The device supports data rates up to 120kbps with typical propagation delays of 10µs. It provides ±15kV ESD protection via the Human Body Model and includes internal pull-up resistors on driver inputs. The component functions within a commercial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar voltage sources.
• High electrostatic discharge protection withstands ±15kV human body model discharges on RS-232 I/O pins.
• Receiver inputs feature guaranteed logic thresholds compatible with both TTL and CMOS logic levels.
• Driver outputs include internal pull-up resistors to ensure defined states when inputs are unconnected.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Hand-held diagnostic tools
• Portable instrumentation systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature rating. Ensure the procurement source provides valid RoHS compliance certificates. Confirm that the delivered components match the exact part number specifications regarding pin configuration and electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-232 communication with high ESD resilience. The narrow SO package is suitable for space-constrained designs. Verify that the system power supply remains within the 4.5V to 5.5V range. Ensure external capacitors meet the specified requirements for the charge pump circuit to maintain signal integrity at maximum data rates.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX202E-MAX213E family of RS-232 transceivers manufactured by Analog Devices Inc./Maxim Integrated. The 'E' designation indicates enhanced ESD protection features compared to standard versions. The 'C' suffix specifies the commercial operating temperature range, while 'SE' denotes the 16-pin narrow small-outline package format.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202EESE+ serves as a direct replacement offering identical functionality with an extended industrial temperature range (-40°C to +85°C). Other family members like the MAX232E provide similar transceiver capabilities but may require different capacitor values or offer additional channels.
