MAX202CSE

Drivers, Receivers, Transceivers Overview

The MAX202CSE is a full RS-232 transceiver featuring two drivers and two receivers, designed for single +5V supply operation. It integrates charge-pump circuitry to generate ±10V internal rails using four external 0.1µF capacitors. The device supports data rates exceeding 120kbps while maintaining EIA/TIA-232E output levels. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 16-pin Narrow SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge-pump voltage converters to eliminate the need for bipolar ±12V supplies
• Maintains guaranteed ±5V minimum output signal levels under worst-case loading conditions
• Provides TTL/CMOS compatible inputs with on-chip pullup resistors for unused driver control

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring single-supply RS-232 communication
• Handheld devices and portable diagnostics equipment
• Applications with limited circuit board space utilizing integrated charge pumps

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm the operating temperature range and package type. The 'C' designation indicates a commercial grade range of 0°C to +70°C. Confirm that the required external components match the datasheet specifications for proper functionality.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and bipolar power rails are undesirable. Ensure the application requires only two transmitter and receiver channels. Verify that the system can accommodate the necessary external 0.1µF capacitors for the internal charge pump operation.

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 for single-supply operation. The MAX202 specifically provides a 2-transmitter, 2-receiver configuration suitable for standard full-duplex serial communication interfaces.
