SN65C3223EDWR

Drivers, Receivers, Transceivers Overview

The SN65C3223EDWR is a fully integrated RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It features two drivers and two receivers housed in a 20-SOIC package with a width of 7.50 mm. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. It functions reliably across an industrial temperature range of -40°C to +85°C. Key electrical specifications include a receiver hysteresis of 500 mV, ensuring noise immunity. The component is RoHS3 compliant and classified under ECCN EAR99.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed data transmission at rates up to 1 Mbps
• Provides full-duplex communication capability with dual drivers and receivers
• Operates on a single power supply ranging from 3 V to 5.5 V
• Includes receiver hysteresis for enhanced signal integrity

Drivers, Receivers, Transceivers Applications

• Industrial equipment requiring robust serial communication
• Portable battery-powered devices utilizing low-voltage operation
• Modems and facsimile machines
• Point-of-sale (POS) terminals and payment systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature grade (-40°C to +85°C). Confirm the 'DWR' suffix corresponds to the 20-SOIC tape and reel packaging format. Ensure compatibility with existing PCB footprints for the 20-SOIC package before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 1 Mbps data rate is required compared to the standard 120 kbps of legacy parts. Choose the SOIC package over SSOP if wider spacing is preferred for assembly. Verify that the 3 V to 5.5 V operating range aligns with the system's power supply rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65C32xx family of RS-232 transceivers, which are pin-to-pin replacements for older MAX3223 series components. It serves as a modern alternative offering higher data rates while maintaining similar interface characteristics. The device integrates charge pump circuitry to generate the necessary voltages for RS-232 signaling without external transformers.

Drivers, Receivers, Transceivers Replacement Considerations

MAX3223EIDBR is a confirmed substitute with identical functionality but a lower maximum data rate of 500 kbps.
