MAX216CPN

Drivers, Receivers, Transceivers Overview

The MAX216CPN is a low-power, single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and integrates charge pumps to generate the necessary positive and negative voltages for RS-232 communication without requiring external dual supplies. The device features two drivers and two receivers, supporting full-duplex data transmission at data rates up to 120 kbps. It utilizes only 0.1 µF external capacitors, significantly reducing board space and component count compared to traditional solutions. The part is housed in a 16-pin PDIP package and is designed for applications requiring reliable serial communication with minimal power consumption.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pumps to eliminate the need for external dual voltage supplies
• Requires only small 0.1 µF external capacitors for operation
• Supports full-duplex communication with two drivers and two receivers
• Operates efficiently from a single +5V power source

Drivers, Receivers, Transceivers Applications

• Portable battery-powered equipment requiring RS-232 connectivity
• Modems and fax machines
• Handheld terminals and POS systems
• Industrial control systems with serial interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CPN' indicates the PDIP-16 package and commercial temperature range when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as legacy parts may have varying environmental certifications. Ensure the supplier provides genuine Analog Devices/Maxim Integrated components to avoid counterfeit risks associated with older interface ICs.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX216CPN when a single +5V supply is available and low external capacitance is required to minimize PCB area. Compare against the MAX202EPE if higher data rates or extended temperature ranges are needed. Ensure the application does not require ESD protection levels exceeding the standard specifications of this family. Verify that the 120 kbps data rate meets the system timing requirements.

Drivers, Receivers, Transceivers Part Context

The MAX216 belongs to the Maxim Integrated MAX21x family of low-power RS-232 transceivers. This series is characterized by its ability to operate from a single supply while providing standard RS-232 voltage levels. The CPN designation specifically refers to the plastic DIP package variant, distinguishing it from surface-mount options like the MAX216CWI. It serves as a drop-in replacement for older dual-supply RS-232 chips in existing designs.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211CPE is a compatible alternative within the same family offering similar functionality. The MAX202EPE is another widely used equivalent but may require different external capacitor values. Verify pin compatibility and electrical specifications before substituting any other RS-232 transceiver.
