GD75232PWRG4

Overview

The GD75232PWRG4 is a Texas Instruments RS-232 transceiver featuring three drivers and five receivers in a 20-TSSOP package. It operates with a single 5V supply for logic and dual supplies ranging from ±7.5V to ±15V for the RS-232 interface. The device supports data rates up to 120Kbps and includes an internal charge pump to generate required voltages without external capacitors. It functions within a commercial temperature range of 0°C to 70°C and offers 500 mV receiver hysteresis for noise immunity.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• Single 5V logic supply simplifies power design
• High noise immunity via 500 mV receiver hysteresis

Applications

• Industrial control systems requiring RS-232 connectivity
• Point-of-sale terminals and barcode scanners
• Medical equipment with serial communication interfaces

Procurement Notes

Verify the suffix G4 indicates lead-free construction compliant with RoHS standards. Confirm the package type matches the 20-TSSOP footprint requirements. Check for obsolescence notices as this component may be subject to lifecycle changes. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this part when a single 5V logic supply is available alongside standard RS-232 voltage levels. The 20-TSSOP package suits space-constrained designs compared to larger DIP options. Consider the 120Kbps speed limit for low-to-medium baud rate applications. Verify that the internal charge pump meets the specific current demands of the application.

Part Context

This component belongs to the GD75232 family, which are pin-compatible replacements for industry-standard MAX232 devices. The GD75232 series maintains the same functionality while offering improved performance characteristics such as lower power consumption and enhanced noise tolerance. It serves as a direct drop-in solution for legacy RS-232 designs.

Replacement Considerations

The SN752232DGGR is a related transceiver but differs significantly in package size (48-TSSOP) and driver/receiver count (3/5). Direct substitution requires careful evaluation of board space and pin compatibility. Other MAX232-compatible parts from different manufacturers may offer similar functionality but require verification of electrical specifications.
