CD74AC652M96 Equivalent & Substitute Parts

Part Overview

The CD74AC652M96 is a non-inverting transceiver logic IC manufactured by Texas Instruments, designed for 8-bit data transmission with 3-state output capability. This device operates across a supply voltage range of 1.5V to 5.5V and is housed in a 24-SOIC surface mount package. The part is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter ranges. Alternative sources become necessary due to inventory availability, supply chain optimization, or design flexibility requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74AC652M96 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Package / Case: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Voltage - Supply: Must encompass or match the 1.5V ~ 5.5V range
• Operating Temperature: Must encompass or match the -55°C ~ 125°C range
• RoHS and REACH compliance status
• Moisture Sensitivity Level

Substitute parts are classified into two categories: Parametric Equivalents (full parameter match) and Manufacturer Recommended alternatives (minor parameter variations within acceptable engineering tolerances).

Parameter Comparison

Engineering Selection Recommendations

CD74AC646M96 (Parametric Equivalent - Preferred Substitute)

The CD74AC646M96 is a direct parametric equivalent to the CD74AC652M96. Both devices are manufactured by Texas Instruments, share identical electrical specifications, and maintain the same supply voltage range (1.5V ~ 5.5V) and operating temperature range (-55°C ~ 125°C). Both parts carry Active product status and ROHS3 compliance with MSL 1 rating. This substitute provides full functional and mechanical interchangeability with no design modifications required.

MC74AC652DWR2G (Manufacturer Recommended - Conditional Substitute)

The MC74AC652DWR2G, manufactured by onsemi, maintains functional equivalence in logic type, element count, bit width, output type, and current specifications. However, this part exhibits parameter variations that require engineering evaluation:

• Supply voltage range is 2V ~ 6V (versus 1.5V ~ 5.5V for the main part)
• Operating temperature range is -40°C ~ 85°C (versus -55°C ~ 125°C for the main part)
• Product status is Obsolete
• Moisture Sensitivity Level is 3 (168 Hours) versus MSL 1 (Unlimited)

This substitute is suitable only for applications where the narrower voltage and temperature ranges are acceptable and where the higher moisture sensitivity level does not conflict with storage or handling requirements. The obsolete status indicates this part is no longer in active production.

Frequently Asked Questions (FAQ)

Q: Can CD74AC646M96 be used as a direct replacement for CD74AC652M96?

A: Yes. The CD74AC646M96 is a parametric equivalent with identical electrical and mechanical specifications. No circuit modifications or design changes are required for substitution.

Q: What are the key differences between CD74AC652M96 and MC74AC652DWR2G?

A: The MC74AC652DWR2G has a narrower supply voltage range (2V ~ 6V versus 1.5V ~ 5.5V), a narrower operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C), higher moisture sensitivity (MSL 3 versus MSL 1), and obsolete product status. Substitution is conditional on application requirements.

Q: Are all substitute parts available in the same 24-SOIC package?

A: Yes. All listed substitute parts use the 24-SOIC (0.295", 7.50mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What does "3-State Output" mean for this transceiver?

A: 3-State output refers to the output capability of the device, which can assume three states: logic high, logic low, or high-impedance (disabled). This allows multiple devices to share a common bus without contention.

Q: Is the MC74AC652DWR2G suitable for industrial temperature applications?

A: No. The MC74AC652DWR2G operates only to 85°C maximum, making it unsuitable for applications requiring the full -55°C ~ 125°C temperature range of the CD74AC652M96.

Q: What is the significance of MSL (Moisture Sensitivity Level)?

A: MSL indicates the maximum time a component can be exposed to moisture at specified temperature and humidity conditions before soldering. MSL 1 (Unlimited) allows indefinite storage, while MSL 3 (168 Hours) requires controlled storage conditions and limits shelf life to 168 hours after moisture exposure.
