Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS96173CN/NOPB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Type: Receiver
• Protocol: RS422, RS485 (minimum requirement)
• Number of Drivers/Receivers: 0/4
• Voltage - Supply: 4.75V ~ 5.25V

Compatible Variation Parameters:

• Receiver Hysteresis: 50 mV to 60 mV (within acceptable tolerance)
• Operating Temperature: 0°C ~ 70°C or extended range (-40°C ~ 85°C)
• Data Rate: 10 Mbps or unspecified (does not restrict substitution)
• Product Status: Active or Obsolete (both acceptable for equivalent parts)

All substitute parts listed maintain electrical and mechanical compatibility within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

SN75173N is the direct equivalent from Texas Instruments with active product status. It maintains identical electrical specifications including 50 mV receiver hysteresis and 4.75V to 5.25V supply voltage. This part is recommended for designs requiring continuity with the original DS96173CN/NOPB specification.

LTC488CN#PBF from Analog Devices Inc. is an active alternative with ROHS3 compliance. The receiver hysteresis specification is 60 mV, which remains within acceptable tolerance for RS422/RS485 applications. This part is suitable for new designs requiring manufacturer diversification.

LTC488IN#PBF from Linear Technology provides extended operating temperature range (-40°C to 85°C) compared to the standard 0°C to 70°C specification. This part is appropriate for applications requiring wider temperature performance. RoHS compliance status is not specified for this variant.

Secondary Substitutes (Obsolete Product Status):

SN75ALS173N from Texas Instruments is classified as obsolete but remains available in inventory. It maintains the 50 mV receiver hysteresis and supports RS422, RS423, and RS485 protocols. This part is suitable only when active alternatives are unavailable or when legacy system compatibility is required.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original DS96173CN/NOPB specifications.

Frequently Asked Questions (FAQ)

Q: Can SN75173N directly replace DS96173CN/NOPB in existing designs?

A: Yes. SN75173N is electrically and mechanically equivalent. Both parts operate at 4.75V to 5.25V, support RS422/RS485 protocols, feature 50 mV receiver hysteresis, and use identical 16-DIP packaging. The primary difference is product status: SN75173N is active while DS96173CN/NOPB is obsolete.

Q: What is the difference between LTC488CN#PBF and LTC488IN#PBF?

A: Both are Analog Devices/Linear Technology equivalents with 60 mV receiver hysteresis. The primary difference is operating temperature range: LTC488CN#PBF operates 0°C to 70°C, while LTC488IN#PBF operates -40°C to 85°C. Packaging differs as well: LTC488CN#PBF is supplied in Tube, while LTC488IN#PBF is supplied in Bulk.

Q: Are all substitute parts ROHS3 compliant?

A: DS96173CN/NOPB, SN75173N, LTC488CN#PBF, and SN75ALS173N are confirmed ROHS3 compliant. LTC488IN#PBF does not specify RoHS status in the provided data.

Q: Does the 60 mV receiver hysteresis in LTC488 parts affect compatibility?

A: No. The 60 mV hysteresis in LTC488CN#PBF and LTC488IN#PBF is within acceptable tolerance for RS422/RS485 receiver applications. Both 50 mV and 60 mV specifications meet standard interface requirements.

Q: Which substitute is recommended for new designs?

A: SN75173N is recommended for new designs requiring Texas Instruments sourcing. LTC488CN#PBF is recommended when manufacturer diversification is required. LTC488IN#PBF is recommended for applications requiring extended temperature operation beyond 0°C to 70°C.

Q: Can I use SN75ALS173N as a substitute?

A: SN75ALS173N is electrically compatible but classified as obsolete. Use only when active alternatives (SN75173N, LTC488CN#PBF, LTC488IN#PBF) are unavailable or when legacy system compatibility is mandatory.
