CD74HCT174M96 Equivalent & Substitute Parts

Part Overview

The CD74HCT174M96 is a D-Type flip-flop logic integrated circuit manufactured by Texas Instruments, featuring 1 element with 6-bit configuration in a 16-SOIC surface mount package. This component functions as a master reset flip-flop with positive edge triggering, operating at clock frequencies up to 25 MHz. The part is currently in active production status with 2612 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative packaging formats are required for manufacturing flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HCT174M96 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• D-Type flip-flop architecture with 1 element and 6-bit configuration
• Positive edge trigger mechanism
• Non-inverted output type
• Voltage supply range of 4.5V ~ 5.5V
• Master reset function

Mechanical Compatibility Requirements:

• 16-SOIC package format (0.154", 3.90mm Width)
• Surface mount mounting type

Compliance Requirements:

• ROHS3 compliance status
• Moisture Sensitivity Level 1 (Unlimited)

Substitute parts must maintain identical functional architecture and package specifications. Variations in clock frequency, propagation delay, quiescent current, and output current are permissible provided the substitute part meets or exceeds the performance envelope of the primary part within the specified voltage and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT174MT (Texas Instruments): This part is a parametric equivalent to the CD74HCT174M96, differing only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel). Both parts are manufactured by Texas Instruments with identical electrical specifications. The CD74HCT174MT is suitable for high-volume production environments where tape and reel packaging is standard. However, this part carries a Last Time Buy product status, indicating limited future availability. Selection of this substitute should account for long-term supply chain requirements.

74HCT174D,653 (NXP Semiconductors): This part is manufactured by NXP Semiconductors and maintains full electrical and mechanical compatibility with the CD74HCT174M96. The NXP part demonstrates superior performance characteristics, including higher clock frequency (69 MHz versus 25 MHz), faster propagation delay (35ns versus 40ns), and lower input capacitance (4.6 pF versus 10 pF). The operating temperature range is narrower (-40°C to 125°C versus -55°C to 125°C). This part is in active production status with higher inventory availability (9829 units). The 74HCT174D,653 is supplied in bulk packaging format. RoHS compliance status is not specified for this part. Selection of this substitute is appropriate when performance enhancement and supply continuity are priorities, provided the narrower temperature range meets application requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT174MT be used as a direct replacement for the CD74HCT174M96?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications and package format. The only difference is the packaging delivery method (Tape & Reel versus Cut Tape & Digi-Reel). However, the CD74HCT174MT carries Last Time Buy status, meaning future availability is limited.

Q: Is the NXP 74HCT174D,653 compatible with the CD74HCT174M96?

A: Yes. The NXP part maintains full electrical and mechanical compatibility. All critical parameters—D-Type architecture, 6-bit configuration, positive edge triggering, non-inverted output, and 16-SOIC package—are identical. The NXP part offers improved performance with higher clock frequency and faster propagation delay. The operating temperature range is narrower (-40°C to 125°C versus -55°C to 125°C), which must be verified against application requirements.

Q: What are the key differences between these substitute parts?

A: The CD74HCT174MT differs from the CD74HCT174M96 only in packaging format and product status. The NXP 74HCT174D,653 differs in clock frequency (69 MHz versus 25 MHz), propagation delay (35ns versus 40ns), input capacitance (4.6 pF versus 10 pF), output low current (5.2mA versus 4mA), operating temperature range (-40°C to 125°C versus -55°C to 125°C), and packaging format (bulk versus cut tape).

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring the full -55°C to 125°C temperature range, the CD74HCT174MT is appropriate, though supply continuity should be confirmed due to Last Time Buy status. For designs operating within -40°C to 125°C, the NXP 74HCT174D,653 offers superior performance and active production status with higher inventory availability.

Q: Are all three parts ROHS3 compliant?

A: The CD74HCT174M96 and CD74HCT174MT are explicitly ROHS3 compliant. RoHS compliance status is not specified in the provided data for the NXP 74HCT174D,653.

Q: What packaging considerations apply to these parts?

A: The CD74HCT174M96 is supplied in Cut Tape & Digi-Reel format suitable for lower-volume or mixed-component assembly. The CD74HCT174MT is supplied in Tape & Reel format for high-volume production. The NXP 74HCT174D,653 is supplied in bulk format. Packaging selection should align with manufacturing process and volume requirements.
