GD75232PWR

Overview

The GD75232PWR is a fully compliant RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It integrates three drivers and five receivers within a single 20-pin TSSOP package. The device supports data rates up to 120 kbps and operates with a supply voltage range of 5V or ±7.5V to 15V. It features a receiver hysteresis of 500 mV to improve noise immunity. The component 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 rejection through built-in receiver hysteresis.
• Supports standard RS-232 voltage levels with flexible power supply options.
• Designed for surface-mount assembly in compact electronic systems.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Modem connections and peripheral interfacing in embedded devices.
• Point-of-sale (POS) terminals and barcode scanners.
• Medical equipment utilizing serial data transmission protocols.

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as indicated by the 'PWR' designation. Ensure compatibility with surface-mount assembly processes by checking the 20-TSSOP footprint dimensions against the PCB layout. Confirm that the selected variant meets the required environmental specifications for the intended operational temperature range.

Selection Notes

Select this component when a high integration level of drivers and receivers is required in a small form factor. The 20-TSSOP package offers a space-efficient solution compared to larger DIP alternatives. Consider the 120 kbps data rate limit and the specific voltage requirements when designing the power supply circuitry for the target application environment.

Part Context

This part belongs to the GD series of interface integrated circuits from Texas Instruments. It serves as a functional equivalent to industry-standard RS-232 transceivers, providing a cost-effective solution for serial communication needs. The device is part of a broader family that includes various package options such as SOIC and SSOP to accommodate different design constraints.

Replacement Considerations

Direct pin-compatible substitutes include the GD75232DBR (SSOP package) and GD75232DWR (SOIC package). Verify that the alternative package type fits the existing PCB footprint before substitution. Other compatible devices may include the SN75189ADR for quad driver applications, though pin counts differ.
