SN65HVD06P Equivalent & Substitute Parts

Part Overview

The SN65HVD06P is a half-duplex RS422/RS485 transceiver IC manufactured by Texas Instruments, housed in an 8-pin DIP package for through-hole mounting. This part is classified as obsolete, though 3615 units remain available in inventory. The obsolete status necessitates identification of active equivalent parts to ensure long-term design continuity and supply chain reliability for new production runs and system updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN65HVD06P is determined by strict equivalence across the following electrical and mechanical parameters:

• Protocol Compatibility: Both parts must support RS422 and RS485 standards
• Transceiver Configuration: 1 driver and 1 receiver (1/1 configuration)
• Duplex Mode: Half-duplex operation
• Electrical Specifications: Identical supply voltage range (4.5V ~ 5.5V), data rate (10 Mbps), receiver hysteresis (35 mV), and operating temperature range (-40°C ~ 85°C)
• Functional Equivalence: Same base product number (65HVD06) ensures identical die and electrical behavior
• Compliance: ROHS3 compliance maintained across substitutes

The SN65HVD06DR qualifies as a direct electrical equivalent, differing only in package form factor and mounting technology while maintaining all functional and electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The SN65HVD06DR is the active equivalent substitute for the obsolete SN65HVD06P. Both parts share identical electrical specifications, functional behavior, and compliance certifications (ROHS3, REACH Unaffected). The SN65HVD06DR maintains active product status with higher inventory availability (5300 units), ensuring supply chain continuity.

Selection between these parts depends on PCB design requirements:

• Through-hole designs: SN65HVD06P remains available for legacy board revisions, though supply is finite
• New designs or surface-mount requirements: SN65HVD06DR is the appropriate choice, offering active status and surface-mount convenience

Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements. The transition from DIP to SOIC packaging requires PCB layout modification but introduces no electrical or functional changes.

Frequently Asked Questions (FAQ)

Q: Can the SN65HVD06DR directly replace the SN65HVD06P in existing designs?

A: Electrically and functionally, yes. The SN65HVD06DR provides identical RS422/RS485 transceiver performance with the same 1/1 driver/receiver configuration, data rate, supply voltage, and operating temperature range. However, the package change from 8-DIP to 8-SOIC requires PCB redesign for surface-mount implementation.

Q: What is the significance of the base product number 65HVD06?

A: The base product number indicates the core die and electrical design are identical across package variants. Parts sharing this base number are functionally equivalent and differ only in packaging and mounting technology.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The SN65HVD06DR has an MSL rating of 1 (Unlimited), while the SN65HVD06P lists MSL as Not Applicable, reflecting the difference between surface-mount and through-hole package handling requirements.

Q: Why is the SN65HVD06P classified as obsolete?

A: Obsolete status reflects Texas Instruments' product lifecycle management. The SN65HVD06DR represents the active continuation of this product line in surface-mount form factor, which aligns with modern manufacturing practices.

Q: Can both parts operate at the same supply voltage and temperature range?

A: Yes. Both parts operate across 4.5V to 5.5V supply voltage and -40°C to 85°C temperature range with identical receiver hysteresis (35 mV) and 10 Mbps data rate specifications.
