GD75232DWR

Overview

The GD75232DWR is a Texas Instruments RS-232 transceiver housed in a 20-pin SOIC package. It features three drivers and five receivers for full-duplex communication with a data rate of 120 kb/s. The device operates on a single 5 V supply, ranging from 4.5 V to 5.5 V, with a maximum operating current of 30 mA. It supports an extended commercial temperature range from 0°C to +70°C. This component lacks integrated ESD protection and is supplied in reel, cut tape, or MouseReel formats.

Feature Summary

• Integrates three independent drivers and five independent receivers within a single IC
• Supports full-duplex serial data transmission at speeds up to 120 kb/s
• Designed for operation with a standard single 5 V power supply

Applications

• RS-232 serial communication interface circuits
• Modem applications requiring multi-driver/receiver configurations
• Industrial control systems utilizing standard RS-232 protocols

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Ensure the ordering part number matches the required SOIC-20 variant. Cross-reference the manufacturer number with authorized distributors to validate authenticity and current production status.

Selection Notes

Select this component when a 20-pin surface-mount solution is required for RS-232 signaling. It is suitable for designs needing three transmit and five receive channels. Verify that the 120 kb/s speed meets system requirements. Check if external ESD protection is necessary as the internal circuitry does not include it. Ensure the 4.5 V to 5.5 V voltage range aligns with the target power supply.

Part Context

This part belongs to the GD75232 series of RS-232 transceivers manufactured by Texas Instruments. It shares functional similarities with other variants like the GD75232DW and GD75232DBR, differing primarily in packaging. The series provides a standardized interface for serial data communication in commercial electronic equipment.

Replacement Considerations

GD75232DW (SOIC-20), GD75232DBR (SSOP-20), GD75232PWR (TSSOP-20). Verify pinout compatibility and package dimensions before substitution.
