SN75ALS164DW Equivalent & Substitute Parts

Part Overview

The SN75ALS164DW 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 suitable alternatives essential for ongoing system support and new design implementations. The transceiver provides eight drivers and eight receivers with 650 mV receiver hysteresis, operating within a 4.75V to 5.25V supply voltage range and 0°C to 70°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN75ALS164DW is determined by the following critical parameters:

Parametric Equivalent Substitutes maintain identical electrical and mechanical specifications:

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

Functional Alternative Substitutes provide equivalent transceiver functionality but with different protocol support, channel configuration, or electrical characteristics. These parts are suitable when system requirements allow protocol flexibility or when channel count reduction is acceptable.

Parameter Comparison

Engineering Selection Recommendations

SN75ALS162DW is the parametric equivalent substitute for direct replacement in IEEE 488 applications. This part maintains identical electrical specifications, channel configuration, and package dimensions. Both parts share obsolete product status, indicating that long-term availability may be limited. Selection of this substitute requires no circuit modifications and provides pin-for-pin compatibility.

SN65C1167ENSR is a functional alternative suitable for applications where protocol flexibility exists. This part is currently in active production status, providing superior long-term availability compared to the obsolete SN75ALS164DW. The SN65C1167ENSR operates with full-duplex capability and supports RS422/RS485 protocols, requiring system-level evaluation for protocol compatibility. The reduced channel count (2/2 versus 8/8) and smaller package footprint (16-SOIC versus 24-SOIC) necessitate circuit redesign. The extended operating temperature range (-40°C to 85°C) and wider supply voltage tolerance (4.5V to 5.5V) provide enhanced environmental performance.

Frequently Asked Questions (FAQ)

Q: Can SN75ALS162DW replace SN75ALS164DW without circuit modifications?

A: Yes. The SN75ALS162DW is a parametric equivalent with identical electrical specifications, channel 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 24-SOIC package. No circuit modifications are required.

Q: Is SN65C1167ENSR a direct replacement for SN75ALS164DW?

A: No. The SN65C1167ENSR is a functional alternative, not a direct replacement. It differs in protocol (RS422/RS485 versus IEEE 488), channel configuration (2/2 versus 8/8), duplex mode (full versus half), receiver hysteresis (60 mV versus 650 mV), and package size (16-SOIC versus 24-SOIC). System-level evaluation and circuit redesign are required.

Q: What is the primary advantage of selecting SN65C1167ENSR over parametric equivalents?

A: The SN65C1167ENSR maintains active product status, ensuring ongoing availability and manufacturing support. Parametric equivalents (SN75ALS162DW) are classified as obsolete, which may result in limited stock and eventual discontinuation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both SN75ALS162DW and SN65C1167ENSR are ROHS3 compliant, matching the compliance status of the SN75ALS164DW.

Q: What package considerations apply when selecting substitutes?

A: The SN75ALS162DW maintains the 24-SOIC package, requiring no PCB layout modifications. The SN65C1167ENSR uses a smaller 16-SOIC package, necessitating PCB redesign and potential layout optimization due to reduced footprint dimensions.
