CD74AC373M96 Equivalent & Substitute Parts

Part Overview

The CD74AC373M96 is a D-Type Transparent Latch logic IC manufactured by Texas Instruments, featuring an 8:8 circuit configuration with tri-state output capability. This component operates across a supply voltage range of 1.5V to 5.5V and is housed in a 20-SOIC surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when alternative packaging formats better suit manufacturing requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74AC373M96 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Independent Circuits: 1
• Current - Output High, Low: 24mA, 24mA

Mechanical Compatibility Requirements:

• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 20-SOIC

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts are grouped into two categories based on manufacturer recommendation status and packaging format. All substitutes maintain identical mechanical footprint and electrical circuit configuration, with variations in supply voltage range, propagation delay, operating temperature, and packaging format (Cut Tape versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

CD74AC573M96 (Texas Instruments, Parametric Equivalent)

This part is a direct parametric equivalent to the CD74AC373M96, differing only in packaging format (Tape & Reel versus Cut Tape). Both parts share identical electrical specifications, operating temperature range (-55°C ~ 125°C), supply voltage range (1.5V ~ 5.5V), and propagation delay (3ns). Both maintain MSL 1 rating and ROHS3 compliance. Selection of this part is appropriate when Tape & Reel packaging format is preferred for automated assembly processes.

MC74AC373DWG and MC74AC373DWR2G (onsemi, Manufacturer Recommended)

These onsemi parts are manufacturer-recommended alternatives with the following considerations:

Supply voltage range is expanded to 2V ~ 6V, providing broader operational capability in systems with higher supply voltages. Propagation delay increases to 7.5ns, which may impact timing-critical applications. Operating temperature range is narrower (-40°C ~ 85°C) compared to the Texas Instruments part. Moisture sensitivity level is MSL 3 (168 Hours), requiring controlled storage and handling procedures. Both parts maintain ROHS3 compliance and identical mechanical footprint.

MC74AC373DWG is packaged in Tube format, suitable for manual assembly or lower-volume applications. MC74AC373DWR2G is packaged in Tape & Reel format, appropriate for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MC74AC373DWG or MC74AC373DWR2G be used as direct replacements for CD74AC373M96?

A: These onsemi parts are electrically compatible substitutes with identical circuit configuration, output type, and mechanical footprint. However, three parameter differences exist: propagation delay (7.5ns versus 3ns), operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C), and moisture sensitivity level (MSL 3 versus MSL 1). Applications operating below -40°C or above 85°C, or requiring the faster 3ns propagation delay, must use the Texas Instruments part or CD74AC573M96.

Q: What is the difference between CD74AC373M96 and CD74AC573M96?

A: These parts are parametric equivalents with identical electrical and thermal specifications. The only difference is packaging format: CD74AC373M96 is supplied in Cut Tape (CT) format, while CD74AC573M96 is supplied in Tape & Reel (TR) format. Selection depends on manufacturing process requirements and inventory management preferences.

Q: Why does MSL rating differ between Texas Instruments and onsemi parts?

A: MSL 1 (unlimited) indicates the component has no moisture sensitivity restrictions and does not require controlled storage conditions. MSL 3 (168 Hours) requires that the component be stored in controlled humidity environments and used within 168 hours of package opening. This difference reflects manufacturing process variations between suppliers and does not affect electrical performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CD74AC573M96, MC74AC373DWG, MC74AC373DWR2G) maintain ROHS3 compliance and REACH Unaffected status, consistent with the main part CD74AC373M96.

Q: Which substitute part should be selected for automated assembly?

A: CD74AC573M96 or MC74AC373DWR2G are both supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly processes. MC74AC373DWG is supplied in Tube format and is not optimized for automated assembly.

Q: Can these parts be used in applications requiring operation below -40°C?

A: No. The onsemi parts (MC74AC373DWG and MC74AC373DWR2G) have a minimum operating temperature of -40°C. Applications requiring operation at -55°C must use CD74AC373M96 or CD74AC573M96, both rated to -55°C.
