SN65HVD24P Equivalent & Substitute Parts

Part Overview

The SN65HVD24P is a half-duplex RS422/RS485 transceiver IC manufactured by Texas Instruments in an 8-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring this functionality. The part operates within a 4.5V to 5.5V supply voltage range and supports data rates up to 3 Mbps with a receiver hysteresis of 130 mV.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN65HVD24P is determined by strict alignment of the following critical parameters:

• Package Type: 8-DIP (0.300", 7.62mm) form factor for direct PCB compatibility
• Protocol Support: RS422 and RS485 functionality
• Duplex Configuration: Half-duplex operation
• Driver/Receiver Count: 1/1 configuration
• Supply Voltage Range: 4.5V ~ 5.5V compatibility
• Operating Temperature Range: -40°C ~ 85°C
• Receiver Hysteresis: 130 mV specification
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The SN65HVD23P qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the SN65HVD23P supports a higher data rate of 25 Mbps compared to the SN65HVD24P's 3 Mbps, this represents an enhancement that maintains backward compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the SN65HVD24P and SN65HVD23P are classified as obsolete products. Selection between these parts should be based on the following criteria:

SN65HVD24P is appropriate for applications where the original design specification explicitly requires 3 Mbps data rate operation and where component-level compatibility with legacy designs is mandatory.

SN65HVD23P is suitable for new designs or system upgrades where the higher 25 Mbps data rate capability provides performance headroom without requiring circuit modifications. Both parts maintain identical electrical characteristics for supply voltage, operating temperature, receiver hysteresis, and package form factor.

Both parts comply with ROHS3 and REACH standards, ensuring regulatory compliance for industrial and commercial applications. The MSL rating difference (1 vs. Not Applicable) does not affect substitution eligibility for standard through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can SN65HVD23P directly replace SN65HVD24P on existing PCBs?

A: Yes. Both parts use identical 8-DIP (0.300", 7.62mm) packaging and pinout. No PCB modifications are required for physical installation.

Q: What is the primary difference between these two parts?

A: The SN65HVD23P supports a maximum data rate of 25 Mbps, while the SN65HVD24P supports 3 Mbps. All other electrical and mechanical specifications are identical.

Q: Are there any supply voltage or temperature range differences?

A: No. Both parts operate within 4.5V to 5.5V supply voltage and -40°C to 85°C temperature ranges.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SN65HVD24P and SN65HVD23P are ROHS3 Compliant and REACH Unaffected.

Q: Why is the SN65HVD24P classified as obsolete?

A: Product status reflects manufacturer discontinuation. The SN65HVD23P remains available as a functional equivalent with enhanced data rate capability.

Q: Can I use SN65HVD23P in a design originally specified for SN65HVD24P?

A: Yes. The higher data rate of SN65HVD23P is backward compatible with applications designed for 3 Mbps operation. No design changes are necessary.
