MAX3222CPWR

Overview

The MAX3222CPWR is a dual-channel RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kbps. The device integrates two drivers and two receivers in a single package. It features a shutdown mode that reduces power consumption to less than 1 µA. The component is housed in a 20-TSSOP surface-mount package and is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates dual drivers and receivers for complete RS-232 communication functionality
• Includes a low-power shutdown mode to minimize energy consumption during idle periods
• Operates reliably across standard 3-V and 5-V power supply rails

Applications

• Industrial control systems requiring serial communication interfaces
• Portable equipment utilizing battery-powered RS-232 connections
• Modems and fax machines needing reliable line driver/receiver circuits

Procurement Notes

Verify the specific suffix 'CPWR' corresponds to the commercial temperature grade (0°C to +70°C) and TSSOP-20 packaging. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with low standby current capabilities. Ensure the application environment remains within the commercial temperature limits of 0°C to +70°C. Verify that the system power supply falls between 3 V and 5.5 V to guarantee proper signal integrity and operation.

Part Context

This part belongs to the MAX3222 family of multichannel RS-232 line drivers and receivers. It shares functional similarities with other devices in the series but differs in temperature rating and package type compared to industrial-grade variants like the MAX3222IDW. The CPWR designation specifically indicates the commercial temperature range and plastic small-outline package.

Replacement Considerations

The MAX3222ECPWR serves as a direct replacement offering extended temperature capability (-40°C to +85°C). Other compatible alternatives include the TRS3223ECPWR for similar pinout requirements. Always verify electrical specifications and thermal ratings match the target application constraints.
