Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74VHC164MTC is determined by strict equivalence across the following parameters: logic type (shift register), bit configuration (8-bit), functional operation (serial to parallel conversion), output type (push-pull), supply voltage range (2V ~ 5.5V), operating temperature range (-40°C ~ 85°C), package type (14-TSSOP), and mounting method (surface mount). Parts meeting all these criteria are classified as direct substitutes. Parts meeting most but not all criteria are classified as similar substitutes, with specific parameter deviations noted.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended Priority Order):

1. 74VHC164MTCX (onsemi) — Active product status with identical electrical and mechanical specifications. Same manufacturer as the obsolete part, ensuring design continuity. ROHS3 compliant. Highest compatibility confidence.

2. SN74LV164APWR (Texas Instruments) — Active product status with complete parameter alignment across all critical specifications. ROHS3 compliant. Largest inventory availability (35,100 pcs). Suitable for new designs and production continuity.

Similar Substitutes (Parameter Deviations):

3. SN74LV164APW (Texas Instruments) — Discontinued at DiGi Electronics but meets all electrical and mechanical parameters. ROHS3 compliant. Use only if inventory is available and long-term supply is not required.

4. 74AHC164PW,118 (NXP Semiconductors) — Classified as similar substitute due to incomplete parameter specification in available data. Highest inventory availability (282,695 pcs). Verify detailed specifications with manufacturer before selection.

Frequently Asked Questions (FAQ)

Q: Can 74VHC164MTCX directly replace 74VHC164MTC without circuit modification?

A: Yes. The 74VHC164MTCX is a direct substitute with identical electrical specifications (2V ~ 5.5V supply, -40°C ~ 85°C operating range), identical logic function (8-bit serial-to-parallel shift register), and identical package (14-TSSOP surface mount). No circuit modifications are required.

Q: What is the difference between 74VHC164MTC and SN74LV164APWR?

A: Both parts are 8-bit serial-to-parallel shift registers in 14-TSSOP packages with identical supply voltage (2V ~ 5.5V) and operating temperature ranges (-40°C ~ 85°C). The primary difference is manufacturer: onsemi (74VHC series) versus Texas Instruments (SN74LV series). Electrical performance is equivalent for the specified parameters.

Q: Why is 74VHC164MTC classified as obsolete?

A: The 74VHC164MTC is listed as obsolete by the manufacturer. Direct substitutes with active product status, such as 74VHC164MTCX and SN74LV164APWR, are recommended for new designs and ongoing production.

Q: Are all substitute parts ROHS3 compliant?

A: The direct substitutes 74VHC164MTCX and SN74LV164APWR are confirmed ROHS3 compliant. The original 74VHC164MTC does not specify RoHS status. Compliance verification is recommended for applications with regulatory requirements.

Q: What is the MSL rating for these parts?

A: All listed parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can 74AHC164PW,118 be used as a substitute?

A: 74AHC164PW,118 is classified as a similar substitute. Complete parameter specifications are not available in the provided data. Manufacturer datasheet verification is required before selection to confirm compatibility with your specific application requirements.
