CD74HC02M96 NOR Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC02M96 is a 4-channel NOR gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part implements four independent 2-input NOR gates on a single die and operates across a 2V to 6V supply voltage range. The device is currently active in production with 7,259 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for functionally equivalent alternatives from different manufacturers that meet the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC02M96 is determined by the following criteria:

Core Functional Parameters (Must Match):

• Logic Type: NOR Gate
• Number of Circuits: 4
• Number of Inputs: 2
• Voltage Supply Range: 2V to 6V
• Input Logic Levels: Low 0.5V–1.8V, High 1.5V–4.2V
• Output Current: 5.2mA / 5.2mA
• Package Type: 14-SOIC surface mount

Allowable Variations:

• Quiescent Current: Up to 2 µA maximum
• Propagation Delay: Up to 15ns at 6V, 50pF load
• Operating Temperature: Minimum -40°C acceptable (original is -55°C)
• Packaging Format: Cut Tape, Tape & Reel, or Tube acceptable for same footprint
• Manufacturer: Any qualified semiconductor manufacturer

Substitutes are grouped by product status (Active, Discontinued, Obsolete) and packaging format to facilitate selection based on availability and manufacturing requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Production (Recommended):

Select from parts with Active status when new designs are being implemented or when inventory replenishment is required. MC74HC02ADR2G and MC74HC02ADG from onsemi offer improved performance characteristics with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 15ns), making them suitable for power-sensitive or timing-critical applications. Both maintain the full -55°C to 125°C operating range.

74HC02D,653 and 74HC02D-Q100,118 from Nexperia USA Inc. are direct functional equivalents with identical electrical specifications to the CD74HC02M96. The 74HC02D-Q100,118 variant includes AEC-Q100 automotive qualification and is supplied in Tape & Reel format for high-volume manufacturing.

MM74HC02MX from onsemi provides equivalent performance with the widest inventory availability (16,095 units) and is available in Cut Tape & Digi-Reel® packaging. Operating temperature range is limited to -40°C to 85°C.

For Specific Packaging Requirements:

MC74HC02ADG is supplied in Tube packaging for applications requiring alternative handling and storage formats.

Parts to Avoid for New Designs:

CD74HC02MT is discontinued at DiGi Electronics and should not be selected for new production. NLV74HC02ADR2G is obsolete and exhibits degraded propagation delay (19ns) compared to the primary part.

Frequently Asked Questions (FAQ)

Q: Can I substitute MC74HC02ADR2G for CD74HC02M96 in my design?

A: Yes. MC74HC02ADR2G is a direct functional substitute. All core parameters match: 4-channel NOR gate, 2-input configuration, 2V–6V supply, identical logic levels, and 14-SOIC package. The onsemi part offers superior performance with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13ns vs. 15ns). Both maintain -55°C to 125°C operating range.

Q: What is the difference between 74HC02D,653 and 74HC02D-Q100,118?

A: Both are Nexperia parts with identical electrical specifications. The primary difference is packaging format: 74HC02D,653 is supplied in Cut Tape & Digi-Reel®, while 74HC02D-Q100,118 is supplied in Tape & Reel format. The 74HC02D-Q100,118 variant includes AEC-Q100 automotive qualification. Select based on your manufacturing process requirements.

Q: Can I use MM74HC02M or MM74HC02MX if my application requires -55°C operation?

A: No. Both MM74HC02M and MM74HC02MX have a minimum operating temperature of -40°C, not -55°C. If your design requires -55°C operation, select CD74HC02M96, CD74HC02MT, MC74HC02ADR2G, MC74HC02ADG, or NLV74HC02ADR2G.

Q: Is NLV74HC02ADR2G suitable as a substitute?

A: NLV74HC02ADR2G is obsolete and exhibits 19ns propagation delay compared to 15ns for the CD74HC02M96. While functionally compatible, this part should not be selected for new designs due to its obsolete status and degraded timing performance.

Q: What packaging formats are available for the 14-SOIC footprint?

A: Available formats include Cut Tape & Digi-Reel® (CD74HC02M96, MC74HC02ADR2G, 74HC02D,653, MM74HC02MX), Tape & Reel (74HC02D-Q100,118), and Tube (MC74HC02ADG). All maintain the same 14-SOIC (0.154", 3.90mm Width) footprint and are interchangeable at the PCB level.

Q: Are all substitutes RoHS3 compliant?

A: Most substitutes are RoHS3 compliant. MM74HC02M does not specify RoHS status in the provided data. Verify RoHS compliance with your supplier if this is a requirement for your application.
