MAX202CSE+

Drivers, Receivers, Transceivers Overview

The MAX202CSE+ is a +5V RS-232 transceiver featuring two drivers and two receivers. It operates within a supply voltage range of 4.5V to 5.5V, supporting data rates up to 120kbps. The device utilizes an integrated charge pump requiring four external 0.1µF capacitors to generate ±10V levels from a single +5V source. It provides full-duplex communication in a 16-pin SOIC package with an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V power supplies
• Maintains ±5V EIA/TIA-232E output signal levels at data rates exceeding 120kbps
• TTL/CMOS compatible inputs with internal pullup resistors on unused driver inputs

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) against the datasheet selector guide. Confirm the 'SE' designation corresponds to the narrow SOIC-16 package. Ensure the '+' suffix confirms compliance with current environmental standards as documented by the manufacturer.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and bipolar rails are not present. The MAX202 requires four external 0.1µF capacitors for operation. Choose the 'C' grade for commercial environments and the 'E' grade if extended industrial temperatures are required.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. These devices share a common architecture utilizing integrated charge pumps to convert a single +5V input into the dual polarities needed for RS-232 signaling, simplifying board design compared to older discrete solutions.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include the MAX202EESE+ for extended temperature ranges and the MAX202CWE+ for wide SOIC packaging options. Verify pin compatibility and capacitor requirements before substitution.
