MAX203CPP

Drivers, Receivers, Transceivers Overview

The MAX203CPP is a +5V RS-232 transceiver from the MAX200-MAX209 family, designed for single-supply operation. It integrates charge-pump circuitry and four 0.1µF capacitors to generate ±10V internal rails without external components. The device features two drivers and two receivers with TTL/CMOS-compatible inputs. It supports data rates exceeding 120kbps while maintaining EIA/TIA-232E output levels under worst-case conditions. The MAX203CPP operates within a commercial temperature range of 0°C to +70°C and is housed in a 20-pin Plastic DIP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates the need for bipolar supplies
• Onboard capacitors reduce board space requirements
• TTL and CMOS input compatibility ensures logic interface flexibility

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Handheld devices with limited circuit board space
• Portable diagnostic equipment needing reliable serial communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CPP indicates the commercial temperature range and plastic DIP package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement. Ensure ordering details match the exact pinout and electrical specifications required for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a compact, single-supply RS-232 solution is required. It is suitable for designs where external capacitors are undesirable due to space constraints. Compare against other family members like the MAX202 if different driver/receiver counts or shutdown features are needed. Verify that the 120kbps maximum data rate meets system timing requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 series of +5V RS-232 transceivers manufactured by Analog Devices Inc./Maxim Integrated. The series shares common architecture but varies in pin count, driver/receiver configuration, and package options. The MAX203 specifically offers a balanced 2-driver, 2-receiver configuration ideal for standard full-duplex serial links.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other variants within the MAX200-MAX209 family such as the MAX202CPE or MAX204CPP, provided pinouts and functional requirements align. Cross-reference datasheets to ensure voltage ranges and package dimensions are compatible with existing PCB layouts.
