GD65232DBRE4

Overview

The GD65232DBRE4 is a full-duplex RS-232 transceiver manufactured by Texas Instruments. It integrates three drivers and five receivers within a single package, supporting 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 utilizes external capacitors for charge pump functionality to generate the necessary voltages for RS-232 signal levels. The component is housed in a 20-pin SSOP package with a width of 5.30 mm and supports surface mount installation. It functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive serial communication interfaces.
• Supports full-duplex operation with standard RS-232 voltage levels generated via internal charge pumps.
• Features receiver hysteresis to improve noise immunity on noisy communication lines.

Applications

• Industrial control systems requiring multiple serial ports
• Modem interface circuits
• Printers and peripheral equipment connections

Procurement Notes

Verify the exact part marking against the manufacturer's official datasheet to confirm the GD65232 family designation. Ensure the suffix 'E4' corresponds to lead-free compliance requirements specified in the ordering information. Cross-reference the 20-SSOP package dimensions to guarantee compatibility with existing PCB footprints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring three transmit and five receive channels on a single RS-232 bus. It is suitable for applications needing 120 kbps throughput without the complexity of separate driver and receiver chips. Consider the 20-SSOP package size constraints and the requirement for external charge pump capacitors during the schematic design phase.

Part Context

This part belongs to the GD series of RS-232 interface integrated circuits produced by Texas Instruments. The GD65232 variant specifically provides a higher channel count compared to standard dual-driver devices, allowing for more complex serial architectures in compact form factors while maintaining industry-standard electrical characteristics.

Replacement Considerations

GD75232DBR is a verified functional substitute within the same family offering identical pinout and specifications.
