GD75232PW

Overview

The GD75232PW is a full-duplex RS-232 transceiver manufactured by Texas Instruments, designed for data communication applications. It integrates three drivers and five receivers within a single package, supporting data rates up to 120 Kbps. The device operates from a single 5V supply or dual supplies ranging from ±7.5V to ±15V. It features a receiver hysteresis of 500 mV to improve noise immunity on noisy lines. The component is housed in a 20-TSSOP package with a width of 4.40mm. It functions reliably across an operating temperature range of 0°C to 70°C and complies with RoHS3 standards.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive RS-232 signal management.
• Provides enhanced noise immunity through a 500 mV receiver hysteresis characteristic.
• Supports flexible power configurations using either a single 5V source or dual asymmetric supplies.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Modem interfacing and peripheral connection in embedded devices.
• Point-to-point data transmission links in commercial equipment.

Procurement Notes

Verify the specific suffix 'PW' corresponds to the 20-TSSOP package variant when sourcing. Confirm that the required operating temperature range aligns with the industrial specification of 0°C to 70°C. Ensure compatibility with the intended power supply architecture, as the device supports both single and dual voltage configurations. Check for RoHS3 compliance requirements if applicable to the target assembly process.

Selection Notes

Select this component when a high pin count interface is necessary due to the inclusion of five receivers alongside three drivers. Consider the TSSOP footprint constraints against available board space, noting the 4.40mm width. Evaluate if the 120 Kbps speed limit meets the system's throughput requirements. Verify that the absence of integrated ESD protection does not conflict with the application's environmental exposure levels.

Part Context

This part belongs to the GD series of RS-232 transceivers from Texas Instruments. It shares functional similarities with other variants like the GD75232PWR and GD75232DBR, differing primarily in packaging style. The base part number GD75232 indicates the core circuit topology, while the suffix defines the physical housing and reel specifications.

Replacement Considerations

Direct substitutes include GD75232PWR (TSSOP) and GD75232DBR (SSOP). Verify pinout compatibility and package dimensions before substitution. Ensure the alternative variant maintains the same 3-driver/5-receiver configuration and electrical characteristics.
