GD65232DBR

Overview

The GD65232DBR is a full-duplex RS-232 transceiver manufactured by Texas Instruments, housed in a 20-SSOP surface-mount package. It integrates three drivers and five receivers to support complex serial communication interfaces. The device operates within a supply voltage range of 5V to ±7.5V–15V and supports data rates up to 120 kbps. Key electrical specifications include a receiver hysteresis of 500 mV for noise immunity and an operating temperature range from 0°C to 70°C. This component is designed for reliable data transmission in industrial and commercial environments requiring robust RS-232 connectivity.

Feature Summary

• Integrates multiple driver and receiver channels for expanded serial port capabilities
• Provides enhanced noise immunity through specified receiver hysteresis
• Supports standard RS-232 protocol for full-duplex communication

Applications

• Industrial control systems requiring multiple serial connections
• Commercial equipment with extended RS-232 interface needs
• Embedded systems utilizing the GD series interface family

Procurement Notes

Verify the manufacturer designation carefully, as the GD prefix may indicate a specific regional or legacy variant distinct from standard TI nomenclature. Confirm the exact pinout and electrical characteristics against the official datasheet before integration. Ensure the 20-SSOP package dimensions match the target PCB footprint. Validate that the 0°C to 70°C operating range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when a single IC must provide more than two transmit and receive lines for RS-232 applications. The 20-SSOP package offers a compact solution for space-constrained designs compared to larger DIP packages. Consider the 120 kbps speed limit and 5V–15V supply requirements to ensure compatibility with the system power rails and baud rate needs. Verify availability of the specific GD prefix variant if standard TI part numbers are not suitable.

Part Context

The GD65232DBR belongs to the GD series of RS-232 interface components, which typically offer higher channel counts than standard dual-driver transceivers. It shares functional similarities with other multi-channel RS-232 devices but is distinguished by its specific driver/receiver configuration and packaging. This part serves as a specialized solution for applications needing consolidated serial I/O without using multiple discrete transceiver chips.

Replacement Considerations

The SN65C3223DBR is listed as a parameter-equivalent alternative, though it features a different driver/receiver count (2/2 vs 3/5). Verify pin-to-pin compatibility and channel requirements before substitution. Other equivalents like TRSF3223EIDBR may also be considered, but their specific electrical parameters and channel configurations must be validated against the original design constraints.
