MAX202CSE-T

Drivers, Receivers, Transceivers Overview

The MAX202CSE-T is a full RS-232 transceiver designed for single +5V supply operation. It integrates charge pump circuitry to generate ±10V internal voltages, eliminating the need for external bipolar supplies. The device features two drivers and two receivers, supporting data rates up to 120kbps. It operates within a voltage range of 4.5V to 5.5V with a typical supply current of 15mA. The component utilizes a 16-pin SOIC package and functions across an industrial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates requirement for external bipolar power supplies
• Maintains 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 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 ordering suffix against manufacturer documentation to confirm packaging format. The 'T' suffix typically indicates tape and reel packaging, whereas other suffixes may denote tube or tray configurations. Confirm that the component matches the required temperature grade and package dimensions specified in the official datasheet before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and bipolar rails are undesirable. Ensure external capacitors meet the recommended 0.1µF specification for proper charge pump operation. Verify that the load capacitance and resistance values remain within the limits defined for the maximum data rate of 120kbps to maintain signal integrity.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. Unlike variants such as the MAX203 or MAX205, it requires four external 0.1µF capacitors for the charge pump. It differs from the MAX201 by providing both positive and negative voltage generation internally rather than relying on an external V+ supply.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include MAX202ESE and MAX202CWE. These parts share identical electrical characteristics and pinouts but differ in operating temperature ranges or package styles.
