GD65232PWR

Overview

The GD65232PWR is a low-power RS-232 transceiver manufactured by Texas Instruments, belonging to the GD series. It integrates three drivers and five receivers in a single package, supporting full-duplex communication with data rates up to 120 kbps. The device operates from a single 5 V supply or dual supplies ranging from ±7.5 V to ±15 V. It features a 20-pin TSSOP package with a width of 4.40 mm. The component functions within an operating temperature range of 0°C to +70°C and includes receiver hysteresis of 500 mV for noise immunity.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive RS-232 interface connectivity.
• Supports full-duplex data transmission at speeds up to 120 kbps.
• Operates on a single 5 V supply or split dual supplies between ±7.5 V and ±15 V.
• Includes 500 mV receiver hysteresis to enhance signal integrity in noisy environments.

Applications

• Industrial control systems requiring serial communication interfaces.
• Embedded devices needing multiple RS-232 ports for peripheral connectivity.
• Data acquisition equipment utilizing standard RS-232 protocols.

Procurement Notes

Verify the specific suffix PWR confirms the 20-TSSOP package and tape-and-reel packaging format. Confirm the manufacturer designation as Texas Instruments to ensure compatibility with the GD series specifications. Check RoHS compliance status and moisture sensitivity level requirements for your assembly process before ordering.

Selection Notes

Select this component when three drivers and five receivers are required in a single IC. Ensure the application voltage aligns with the 5 V single supply or ±7.5 V to ±15 V dual supply options. Verify that the 120 kbps maximum data rate meets the system's communication speed requirements and that the 0°C to +70°C industrial temperature range is sufficient for the operating environment.

Part Context

The GD65232PWR is part of the GD series of RS-232 transceivers from Texas Instruments. It shares functional similarities with the GD75232 but is distinguished by its specific driver and receiver count configuration. This series provides a compact solution for integrating multiple serial ports into space-constrained designs without requiring external charge pumps.

Replacement Considerations

GD75232PWR is a related variant within the same family. Verify pinout compatibility and electrical parameter alignment before substitution. Other generic RS-232 transceivers may require circuit redesign due to differences in driver/receiver counts or supply voltage ranges.
