GD75232N

Overview

The GD75232N is a Texas Instruments RS-232 transceiver housed in a 20-pin PDIP package. It integrates three independent drivers and five receivers for full-duplex communication. The device operates on a single 5 V supply with an operating current of 30 mA. It supports data rates up to 120 kb/s within a commercial temperature range of 0°C to +70°C. Designed for EIA-232-D compliance, it interfaces directly with TTL and DTL logic circuits without requiring external charge pumps or negative voltage supplies.

Feature Summary

• Integrates three drivers and five receivers in a single monolithic package
• Operates from a single positive power supply eliminating need for dual voltages
• Input compatible with standard TTL and DTL logic families
• Provides full-duplex data transmission capability

Applications

• Interfacing between data terminal equipment and data communication equipment
• Serial port implementations in industrial control systems
• Point-to-point communication links requiring multiple transmit and receive lines

Procurement Notes

Verify the specific suffix N indicates the PDIP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation as requirements vary by region. Ensure ordering specifications match the required lead times for through-hole components. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a through-hole solution is required for RS-232 applications. Compare against surface-mount variants like the GD75232DWR if PCB space constraints allow. Evaluate the 120 kb/s speed limit against system requirements. Consider the absence of built-in ESD protection when designing input circuitry for harsh environments.

Part Context

This part belongs to the GD75232 series of RS-232 interface integrated circuits manufactured by Texas Instruments. The series includes various package options such as SOIC, TSSOP, and SSOP to accommodate different mounting styles. All variants share identical electrical characteristics and functionality, differing only in physical footprint and termination type.

Replacement Considerations

GD75232DW serves as a direct surface-mount replacement offering identical electrical performance in a smaller form factor. GD75232PWR provides the same functionality in a TSSOP package for high-density board layouts. Verify pin compatibility before substituting these variants into existing through-hole footprints.
