SN75C3222EDWRG4

Drivers, Receivers, Transceivers Overview

The SN75C3222EDWRG4 is a fully duplex RS-232 transceiver featuring two drivers and two receivers in a 20-pin SOIC package. It operates from a single 3-V to 5.5-V supply with data rates up to 1000 kbit/s. The device includes an internal charge pump requiring four external 0.1 μF capacitors. It provides ±15-kV HBM ESD protection on serial port pins and meets TIA/EIA-232-F standards. The part supports low standby current of 1 μA typical and accepts 5-V logic inputs when powered by a 3.3-V supply.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge pump circuit for single-supply operation
• High electrostatic discharge protection on bus interface pins
• Power-down mode capability for reduced standby consumption
• Logic input compatibility across 3.3-V and 5-V supply voltages

Drivers, Receivers, Transceivers Applications

• Industrial PCs
• Wired Networking equipment
• Data center and networking infrastructure
• Notebook computers
• Hand-held portable devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as obsolete or end-of-life through official Texas Instruments channels before finalizing design-in decisions. Confirm that the G4 suffix indicates RoHS compliance and green material classification. Ensure the DW package variant matches the required PCB footprint and thermal management specifications for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-232 communication with robust ESD protection. Verify that the operating temperature range of 0°C to 70°C aligns with the system requirements. Consider the external capacitor count and board space needed for the charge pump circuitry when evaluating layout constraints compared to integrated capacitor alternatives.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SN75C3222E family, which serves as a drop-in replacement for industry-standard two-driver, two-receiver functions. The SN75C3222EDWRG4 specifically denotes the commercial grade version housed in a 20-pin wide SOIC package with lead-free termination and environmental compliance markings.
