GD65232N

Overview

The GD65232N is a full-duplex RS-232 transceiver manufactured by Texas Instruments. It integrates three drivers and five receivers on a single chip, facilitating easy interface between UARTs and serial-port connectors for IBM PC/AT systems. The device operates with a supply voltage of 5V and supports input voltages from ±7.5 V to 15 V. It features a data rate of 120Kbps and receiver hysteresis of 500mV. The component is housed in a 20-pin PDIP package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates three drivers and five receivers for full-duplex communication
• Provides robust serial interface compatibility with IBM PC/AT systems
• Includes receiver hysteresis for noise immunity

Applications

• IBM PC/AT and compatible computer serial port interfaces

Procurement Notes

Verify the obsolete status of the GD65232N before procurement. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any substitute components meet the original electrical specifications and pinout requirements. Check for lead-free compliance if required by project standards. Validate package integrity upon receipt.

Selection Notes

Select this component for legacy IBM PC/AT system designs requiring integrated RS-232 transceivers. Consider the 120Kbps data rate limit when evaluating high-speed communication needs. Verify that the 20-pin DIP package fits the existing PCB layout constraints. Assess thermal performance within the specified -40°C to 85°C range for the intended environment.

Part Context

The GD65232N belongs to the family of multiple RS-232 drivers and receivers produced by Texas Instruments. It is designed to replace discrete transistor solutions, simplifying circuit design for standard serial communications. The part is classified as an analog mixed-signal line transceiver. Its bipolar technology ensures reliable operation in industrial and commercial computing environments.

Replacement Considerations

The GD665232DWR is listed as a similar available substitute. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement meets the same RS-232 standards and package dimensions.
