GD65232DBRE4 Equivalent & Substitute Parts

Part Overview

The GD65232DBRE4 is a full-duplex RS232 transceiver IC manufactured by Texas Instruments, featuring 3 drivers and 5 receivers in a 20-SSOP surface mount package. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations. The part operates across a wide supply voltage range (5V, ±7.5V ~ 15V) and supports data rates up to 120 kbps with a receiver hysteresis of 500 mV.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GD65232DBRE4 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Protocol Compatibility: RS232 full-duplex transceiver
• Driver/Receiver Configuration: 3 drivers and 5 receivers
• Package Type: Surface mount with compatible pinout
• Electrical Specifications: Supply voltage range, data rate, receiver hysteresis, and operating temperature range
• Compliance Standards: RoHS3 compliance and MSL rating

Two substitute categories exist:

Category 1 - Same Manufacturer (Texas Instruments): GD65232DWR maintains identical electrical specifications and base product lineage but differs in package form factor (20-SOIC vs. 20-SSOP).

Category 2 - Alternative Manufacturer (Analog Devices Inc./Maxim Integrated): MAX3185EAP+ and MAX3185EAP+T provide equivalent RS232 transceiver functionality with 3/5 driver/receiver configuration in the same 20-SSOP package. These parts feature enhanced specifications including higher data rate (230 kbps vs. 120 kbps) and tighter supply voltage tolerance (4.5V ~ 5.5V vs. 5V, ±7.5V ~ 15V).

Parameter Comparison

Engineering Selection Recommendations

For Direct Package Replacement (20-SSOP): MAX3185EAP+T is the preferred substitute. This part maintains identical package geometry and pinout compatibility with the GD65232DBRE4 while offering active product status, ensuring long-term availability and supply chain stability. The enhanced data rate (230 kbps) and tighter supply voltage specification (4.5V ~ 5.5V) provide improved performance margins for new designs.

For Alternative Package Consideration (20-SOIC): GD65232DWR provides equivalent electrical performance and maintains Texas Instruments manufacturer continuity. This option requires PCB layout modification to accommodate the larger 20-SOIC package footprint but preserves the original supply voltage range and data rate specifications.

Compliance Verification: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can MAX3185EAP+ be used as a direct replacement for GD65232DBRE4?

A: Yes. Both parts feature identical 20-SSOP package geometry, 3/5 driver/receiver configuration, full-duplex RS232 operation, and -40°C ~ 85°C operating temperature range. The MAX3185EAP+ offers enhanced specifications (230 kbps data rate vs. 120 kbps) and active product status. Supply voltage differs: MAX3185EAP+ operates at 4.5V ~ 5.5V, while GD65232DBRE4 operates at 5V, ±7.5V ~ 15V. Verify your system supply voltage before substitution.

Q: What is the difference between MAX3185EAP+ and MAX3185EAP+T?

A: Both parts are electrically identical. The primary difference is packaging: MAX3185EAP+ is supplied in Tube packaging, while MAX3185EAP+T is supplied in Tape & Reel (TR) format. Selection depends on procurement volume and assembly line requirements.

Q: Why is GD65232DWR listed as a substitute if it uses a different package?

A: GD65232DWR maintains identical electrical specifications and base product lineage with the GD65232DBRE4. While the 20-SOIC package differs from the 20-SSOP package, it provides a Texas Instruments alternative for applications where package form factor change is acceptable. PCB redesign is required for this substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. GD65232DWR, MAX3185EAP+, and MAX3185EAP+T are all ROHS3 compliant with MSL Level 1 rating, meeting standard environmental and manufacturing requirements.

Q: What is the impact of different receiver hysteresis values?

A: GD65232DBRE4 features 500 mV receiver hysteresis, while MAX3185EAP+ and MAX3185EAP+T feature 650 mV hysteresis. Higher hysteresis improves noise immunity in electrically noisy environments but may reduce sensitivity to weak input signals. Verify your application's signal integrity requirements before substitution.

Q: Can I use these parts interchangeably in existing designs?

A: Direct package-compatible substitution (20-SSOP to 20-SSOP) requires no PCB modification. Verify supply voltage compatibility with your system design. For GD65232DWR (20-SOIC), PCB layout modification is necessary. All parts maintain identical pinout and electrical protocol compatibility for RS232 communication.
