MAX3222CAP

Overview

The MAX3222CAP is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +5.5V supply and includes an internal dual charge pump requiring only four 0.1µF external capacitors. The device features two drivers and two receivers, supporting full-duplex communication with a guaranteed data rate of 120kbps at standard loads. It provides shutdown functionality with typical supply current below 1µA. The component is housed in a 20-pin SSOP package and is rated for commercial operating temperatures ranging from 0°C to +70°C.

Feature Summary

Integrated dual charge pump eliminates the need for bipolar ±12V supplies
Shutdown mode reduces supply current to less than 1µA while maintaining receiver activity
Compatible with industry-standard MAX242 pinout and functionality

Applications

Battery-powered equipment
Hand-held devices
Peripherals
Datacom equipment

Procurement Notes

Verify the specific suffix 'CAP' corresponds to the 20-pin SSOP package and the 'C' grade indicating the 0°C to +70°C temperature range. Confirm lead-free status via the '+' designation. Ensure the ordering code matches the exact manufacturer part number to avoid functional mismatches with other variants in the series.

Selection Notes

Select this component when interfacing TTL/CMOS logic with RS-232 ports under single-supply conditions. It serves as a direct replacement for legacy MAX232 designs where board space savings and lower power consumption are priorities. Verify that the application load does not exceed the specified 120kbps guarantee without derating considerations.

Part Context

This device belongs to the MAX3222/MAX3232/MAX3237/MAX3241 family of low-power RS-232 transceivers. While sharing the same core architecture and charge-pump technology, the MAX3222 specifically provides two drivers and two receivers. Other family members offer different channel counts or higher speed capabilities like MegaBaud operation.

Replacement Considerations

Public confirmed substitutes include MAX3222EAP+ (extended temperature) and MAX3222CUP+ (TSSOP package). Direct replacements must maintain the 20-pin SSOP form factor and 0°C to +70°C rating.
