Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74VHC164MX is determined by strict alignment with the following critical parameters:

• Logic Type: Shift Register (1 Element, 8 Bit)
• Function: Serial to Parallel conversion
• Output Type: Push-Pull configuration
• Voltage Supply Range: 2V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package: 14-SOIC surface mount form factor
• Electrical and mechanical compatibility within these specifications

The identified substitute parts maintain identical functional specifications and package geometry, enabling direct replacement in existing circuit designs without layout or schematic modifications.

Parameter Comparison

Engineering Selection Recommendations

SN74LV164ADR (Texas Instruments) is the primary direct substitute for the 74VHC164MX. This part maintains complete electrical and mechanical compatibility, including identical voltage supply range (2V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and 14-SOIC package specification. The SN74LV164ADR holds active product status with ROHS3 compliance and MSL Level 1 rating, ensuring availability and regulatory alignment for current production applications.

74AHC164D,118 (NXP Semiconductors) is classified as an upgrade alternative. While this part shares the core shift register functionality and 8-bit configuration, complete electrical parameter specifications are not provided in the available data. Selection of this part requires verification of voltage supply range and operating temperature compatibility with the original design requirements.

For applications requiring immediate component availability and guaranteed parameter compatibility, the SN74LV164ADR is the recommended selection. The 74AHC164D,118 may be considered only when full technical specifications have been cross-referenced with design requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV164ADR be used as a direct replacement for the 74VHC164MX without circuit modifications?

A: Yes. The SN74LV164ADR maintains identical electrical specifications (2V ~ 5.5V supply, -40°C ~ 85°C operating range) and package geometry (14-SOIC). No schematic or PCB layout changes are required for substitution.

Q: Why is the 74VHC164MX classified as obsolete?

A: The 74VHC164MX has reached end-of-life status with the manufacturer. Active alternatives from other manufacturers ensure continued design support and component availability.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: logic type (shift register), bit configuration (8-bit), function (serial-to-parallel), output type (push-pull), voltage supply range (2V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package form factor (14-SOIC surface mount).

Q: Is the SN74LV164ADR available in the same packaging options as the 74VHC164MX?

A: The SN74LV164ADR is supplied in Tape & Reel (TR) packaging, while the 74VHC164MX was available in standard surface mount configuration. Both use the identical 14-SOIC package geometry, ensuring mechanical compatibility on PCBs.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the SN74LV164ADR and 74AHC164D,118 are ROHS3 compliant with MSL Level 1 rating, meeting current environmental and regulatory requirements.

Q: What is the difference between the 74VHC, 74LV, and 74AHC series designations?

A: These designations indicate different logic families from different manufacturers. The 74VHC is onsemi's family, 74LV is Texas Instruments' family, and 74AHC is NXP's family. All three families maintain compatible functional specifications for this shift register application.
