SN75C3222DBRE4

Drivers, Receivers, Transceivers Overview

The SN75C3222DBRE4 is a dual-channel RS-232 transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V, supporting standard 3.3 V and 5 V logic levels. The device provides full-duplex communication with two drivers and two receivers, achieving data rates up to 1 Mb/s. Key electrical specifications include a maximum quiescent current of 1 mA, an ESD protection rating of 15 kV, and a propagation delay of 0.3 µs. It functions reliably across an industrial temperature range from 0°C to +70°C and is housed in a 16-pin SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Dual-channel full-duplex RS-232 line driver and receiver configuration
• Low-power operation with 1 mA maximum quiescent current
• High electrostatic discharge (ESD) protection capability
• Compatible with standard 3-V to 5.5-V power supplies

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring robust serial communication
• Portable battery-powered equipment due to low power consumption
• Modems and fax machines utilizing RS-232 interfaces
• Point-of-sale (POS) terminals and barcode scanners

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, specifically the 16-pin SSOP variant. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the datasheet for any recent product change notices or lifecycle status updates.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is needed with low standby current. It is suitable for designs requiring 1-Mb/s data rates without shutdown functionality. Compare against single-channel alternatives if pin count is constrained. Verify that the 15-kV ESD rating satisfies the system's electromagnetic compatibility requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75C322x series of RS-232 transceivers from Texas Instruments. The series offers various channel configurations and package options. The 'E4' suffix typically denotes environmental compliance features such as lead-free construction. It serves as a direct replacement for older industry-standard RS-232 drivers while offering improved power efficiency.
