SN75ALS162DW Equivalent & Substitute Parts

Part Overview

The SN75ALS162DW is an 8/8 half-duplex transceiver designed for IEEE 488 protocol applications in a 24-SOIC surface mount package. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, design updates, and procurement continuity. Substitute parts must maintain functional compatibility through matching electrical characteristics and protocol support while accommodating modern active alternatives where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the SN75ALS162DW is based on the following critical parameters:

Parametric Equivalents maintain identical or near-identical electrical and functional characteristics:

• Protocol: IEEE 488
• Driver/Receiver Configuration: 8/8
• Duplex Mode: Half
• Receiver Hysteresis: 650 mV
• Package Type: 24-SOIC
• Supply Voltage Range: 4.75V ~ 5.25V
• Operating Temperature: 0°C ~ 70°C

Functional Alternatives provide equivalent transceiver capability but operate under different protocols or configurations:

• Alternative protocols (RS422, RS485) with different driver/receiver counts
• Different duplex modes (Full vs. Half)
• Modified electrical specifications (hysteresis, voltage ranges, temperature ratings)
• Different package footprints

The SN75ALS164DW qualifies as a parametric equivalent due to matching protocol, configuration, hysteresis, voltage supply, temperature range, and package specifications. The SN65C1167ENSR functions as a manufacturer-recommended alternative despite protocol and configuration differences, suitable for applications where RS422/RS485 compatibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

SN75ALS164DW is the primary parametric equivalent for direct replacement of the SN75ALS162DW. Both parts share identical electrical specifications, protocol support, package footprint, and thermal characteristics. Both parts carry obsolete status; however, inventory availability may differ. Selection between these two parametric equivalents depends solely on component availability and procurement lead times.

SN65C1167ENSR is designated as the manufacturer-recommended alternative and represents an active product with extended availability. This part operates under RS422/RS485 protocols rather than IEEE 488, features full-duplex operation instead of half-duplex, and provides a reduced driver/receiver count (2/2 versus 8/8). The SN65C1167ENSR is suitable only for applications where protocol migration to RS422/RS485 is feasible and where the reduced channel count meets system requirements. This part offers superior temperature range (-40°C ~ 85°C) and extended supply voltage tolerance (4.5V ~ 5.5V) compared to the main part.

All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN75ALS164DW directly replace the SN75ALS162DW without circuit modifications?

A: Yes. The SN75ALS164DW is a parametric equivalent with identical electrical specifications, protocol support (IEEE 488), driver/receiver configuration (8/8), duplex mode (half), receiver hysteresis (650 mV), supply voltage range (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and package footprint (24-SOIC). No circuit modifications are required.

Q: Is the SN65C1167ENSR a direct replacement for the SN75ALS162DW?

A: No. The SN65C1167ENSR operates under different protocols (RS422/RS485 versus IEEE 488), features full-duplex instead of half-duplex operation, and provides only 2/2 drivers/receivers instead of 8/8. This part is suitable only if your application can accommodate protocol migration and reduced channel count. Circuit modifications will be necessary.

Q: Why does the SN65C1167ENSR have different electrical specifications?

A: The SN65C1167ENSR is designed for RS422/RS485 serial communication standards, which have different electrical requirements than IEEE 488. Receiver hysteresis is 60 mV (versus 650 mV), supply voltage range is broader (4.5V ~ 5.5V), and operating temperature range is extended (-40°C ~ 85°C). These differences reflect the distinct application domains of these transceiver families.

Q: What is the package footprint difference between these parts?

A: The SN75ALS162DW and SN75ALS164DW both use 24-SOIC packages (0.295", 7.50mm width). The SN65C1167ENSR uses a smaller 16-SOIC package (0.209", 5.30mm width). PCB layout modifications are required if substituting with the SN65C1167ENSR.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with modern manufacturing and environmental standards.

Q: Which part should I select if availability is a concern?

A: The SN65C1167ENSR carries active product status with higher reported inventory (9508 pcs), compared to the obsolete status of both the SN75ALS162DW and SN75ALS164DW. If protocol migration is feasible for your application, the SN65C1167ENSR offers superior long-term availability and supply chain stability.
