CD74HC7046AM96 Equivalent & Substitute Parts

Part Overview

The CD74HC7046AM96 is a Phase Lock Loop (PLL) integrated circuit manufactured by Texas Instruments, designed for clock and timing applications. This 16-SOIC surface mount device operates across a supply voltage range of 2V to 6V and supports maximum frequencies up to 38MHz. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative components may be required due to inventory constraints, application-specific packaging needs, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HC7046AM96 is determined by the following critical parameters:

Parametric Equivalent Substitutes maintain identical electrical and mechanical specifications:

• Same device type (Phase Lock Loop IC)
• Identical package format (16-SOIC)
• Matching frequency range (38MHz maximum)
• Equivalent supply voltage range (2V ~ 6V)
• Same input/output logic family (CMOS)
• Identical operating temperature range (-55°C ~ 125°C)

Manufacturer Recommended Alternatives may differ in functional category but are listed as approved substitutes by the original manufacturer. These parts require engineering evaluation for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

CD74HC7046AMT is the direct parametric equivalent to CD74HC7046AM96. Both devices are manufactured by Texas Instruments, share identical electrical specifications, and are packaged in the same 16-SOIC format. This substitute maintains full compatibility for Phase Lock Loop applications requiring 38MHz operation across 2V to 6V supply ranges. Both parts carry ROHS3 compliance and active product status.

74HCT04D,653 is listed as a manufacturer-recommended alternative but represents a different functional category (Inverter logic versus Phase Lock Loop). This part operates within a narrower supply voltage range (4.5V ~ 5.5V) and does not provide PLL functionality. Selection of this alternative requires application-level engineering review to confirm functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD74HC7046AMT be used as a direct replacement for CD74HC7046AM96?

A: Yes. Both parts are Phase Lock Loop ICs from Texas Instruments with identical electrical parameters, frequency ratings, supply voltage ranges, and 16-SOIC packaging. No circuit modifications are required.

Q: What are the key differences between CD74HC7046AM96 and 74HCT04D,653?

A: These are fundamentally different device types. CD74HC7046AM96 is a Phase Lock Loop IC, while 74HCT04D,653 is a logic inverter. The 74HCT04D,653 operates at a narrower supply voltage range (4.5V ~ 5.5V versus 2V ~ 6V) and does not provide PLL functionality. Direct substitution is not applicable without circuit redesign.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CD74HC7046AMT and 74HCT04D,653 are both ROHS3 compliant, matching the compliance status of the primary part.

Q: What is the operating temperature range difference between the main part and 74HCT04D,653?

A: CD74HC7046AM96 operates from -55°C to 125°C, while 74HCT04D,653 operates from -40°C to 125°C. The 74HCT04D,653 has a narrower low-temperature operating range.

Q: Are there packaging differences between the substitute parts?

A: CD74HC7046AMT uses the same 16-SOIC package as CD74HC7046AM96. The 74HCT04D,653 uses a 14-SOIC package, which has different pin counts and pinout configurations. PCB layout modifications would be required if using the 14-SOIC alternative.
