GD75232DWRG4

Overview

The GD75232DWRG4 is a Texas Instruments RS-232 interface integrated circuit featuring three drivers and five receivers. It operates with a single 5V supply alongside dual supplies ranging from ±7.5V to ±15V. The device supports data rates up to 120Kbps and includes 500mV hysteresis on the receivers for noise immunity. Packaged in a 20-pin SOIC (DW) format, it functions within an industrial temperature range of 0°C to 70°C. This component complies with RoHS3 standards and is designated as a full-duplex transceiver suitable for serial communication applications.

Feature Summary

• Integrates multiple RS-232 drivers and receivers into a single package
• Operates reliably with standard single 5V power supply configurations
• Provides receiver input hysteresis to enhance signal integrity in noisy environments

Applications

• Industrial control systems requiring robust serial communication
• Data acquisition equipment utilizing RS-232 protocols
• Embedded systems interfacing with legacy serial peripherals

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and environmental adherence before procurement. Confirm the package type matches the design footprint requirements. Ensure the operating temperature range aligns with the target application environment. Cross-reference the manufacturer part number against official distributor catalogs to confirm current availability status.

Selection Notes

Select this component when a high channel count with five receivers and three drivers is required. It is appropriate for designs needing a single 5V supply option rather than complex dual-rail generation. Consider the 120Kbps speed limit when evaluating higher baud rate needs. The 20-pin SOIC package offers a balance between pin count and board space constraints.

Part Context

This part belongs to the GD series of RS-232 transceivers manufactured by Texas Instruments. It serves as a variant of the GD75232 family, distinguished by its specific packaging and environmental compliance markings. The device complements other interface solutions like the TRS3223 or SN752232 by offering a different driver-to-receiver ratio optimized for specific bus topologies.

Replacement Considerations

The GD75232DWR is a direct functional equivalent without the environmental suffix. The GD75232PWR provides identical electrical characteristics but utilizes a TSSOP package instead of SOIC. Designers must verify pin compatibility and thermal performance when substituting these variants.
