CD74AC174M Equivalent & Substitute Parts

Part Overview

The CD74AC174M is a hex D-type flip-flop logic integrated circuit manufactured by Texas Instruments. This device functions as a master reset flip-flop with six bit-per-element configuration and operates at a maximum clock frequency of 95 MHz. The CD74AC174M is classified as an active product and is suitable for digital logic applications requiring edge-triggered flip-flop functionality in surface mount packaging.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging requirements necessitate alternative configurations.

Substitute Part Grouping Explanation

Substitute parts for the CD74AC174M are identified based on electrical and mechanical parameter equivalence within the 74AC logic series. The substitution criteria are strictly limited to the following parameters:

• Identical functional classification (D-Type Flip-Flop)
• Matching number of elements (1) and bits per element (6)
• Identical clock frequency specification (95 MHz)
• Matching propagation delay characteristics (13.5 ns @ 5V, 50pF)
• Identical trigger type (Positive Edge)
• Matching output type (Non-Inverted)
• Identical output current ratings (24 mA, 24 mA)
• Matching supply voltage range (1.5V ~ 5.5V)
• Identical quiescent current specification (8 µA)
• Matching input capacitance (10 pF)
• Identical operating temperature range (-55°C ~ 125°C)
• Compatible package format (16-SOIC surface mount)

The CD74AC174M96 qualifies as a direct substitute based on complete electrical parameter equivalence and identical package specifications. The primary distinction between these parts is the packaging configuration: the main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both the CD74AC174M and CD74AC174M96 are active products from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts is determined by procurement and assembly requirements rather than functional performance.

The CD74AC174M96 is supplied in Tape & Reel (TR) packaging format and carries RoHS3 compliance certification with Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). This configuration is suitable for high-volume automated assembly operations where tape and reel packaging is standard.

The CD74AC174M is supplied in standard packaging format and is suitable for applications where tape and reel configuration is not required.

Both parts maintain REACH Unaffected status and are suitable for equivalent circuit implementation without functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC174M96 be used as a direct replacement for the CD74AC174M?

A: Yes. The CD74AC174M96 is electrically and mechanically equivalent to the CD74AC174M.
