74HCT08S14-13 Equivalent & Substitute Parts

Part Overview

The 74HCT08S14-13 is a 4-channel AND gate logic IC manufactured by Diodes Incorporated in 14-SOIC surface mount packaging. This device is currently active in production and widely used in digital logic applications requiring AND gate functionality. Substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for cost optimization, or when design flexibility demands parts from different manufacturers while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HCT08S14-13 is determined by the following criteria:

Mandatory Matching Parameters:

• Logic Type: AND Gate
• Number of Circuits: 4
• Number of Inputs: 2
• Package Type: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Base Product Number: 74HCT08 series

Allowable Variation Parameters:

• Voltage Supply Range: Must encompass or match 4.5V ~ 5.5V
• Operating Temperature: May extend beyond -40°C ~ 125°C
• Current specifications: Quiescent and output current may vary within acceptable logic levels
• Propagation Delay: May vary within acceptable timing margins
• Packaging format: Tape & Reel, Cut Tape, or Tube acceptable for same package type
• Product Status: Active or Discontinued at DiGi Electronics acceptable; Obsolete parts listed for reference only

All substitute parts listed maintain identical pinout, logic function, and electrical interface compatibility with the 74HCT08S14-13.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

MC74HCT08ADR2G (onsemi) is the preferred substitute when extended voltage range (2V ~ 6V) and lower quiescent current (1 µA) provide system advantages. This part offers superior propagation delay performance (17ns) and extended temperature range (-55°C ~ 125°C).

CD74HCT08M96 (Texas Instruments) is recommended for applications requiring extended temperature range (-55°C ~ 125°C) while maintaining standard voltage supply specifications (4.5V ~ 5.5V). High inventory availability (27,700 pcs) supports production continuity.

SN74HCT08DR (Texas Instruments) provides direct functional equivalence with standard voltage and temperature specifications. Suitable for applications with -40°C ~ 85°C operating requirements.

MM74HCT08MX (Fairchild Semiconductor) offers enhanced output current capability (4.8mA) and faster propagation delay (18ns) for timing-critical applications within -40°C ~ 85°C range.

Secondary Substitutes (Discontinued or Obsolete Status):

CD74HCT08ME4 and SN74HCT08D are discontinued at DiGi Electronics but remain available through alternative distribution channels. These parts maintain ROHS3 compliance and are suitable for legacy system support or non-production applications.

CD74HCT08M (Harris Corporation) is obsolete and RoHS non-compliant. Use only when legacy system compatibility is mandatory and no alternative exists.

Frequently Asked Questions (FAQ)

Q: Can I substitute MC74HCT08ADR2G for 74HCT08S14-13 in a 5V system?

A: Yes. MC74HCT08ADR2G operates across 2V ~ 6V, which encompasses the 5V operating point. The part maintains identical logic function, pinout, and 14-SOIC package compatibility. Extended voltage range provides additional design flexibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both packaging formats contain identical die and electrical specifications. Tape & Reel is optimized for automated assembly lines with continuous feed capability. Cut Tape & Digi-Reel is suitable for lower-volume applications or manual assembly. Package type (14-SOIC) remains identical.

Q: Is CD74HCT08M suitable for new designs?

A: No. CD74HCT08M is obsolete and RoHS non-compliant. Use only for legacy system maintenance when no alternative exists. All active substitutes listed above are ROHS3 compliant and suitable for new designs.

Q: How do I select between multiple active substitutes?

A: Selection depends on application requirements. For extended temperature range, choose CD74HCT08M96 or MC74HCT08ADR2G. For faster propagation delay, select MC74HCT08ADR2G (17ns) or MM74HCT08MX (18ns). For standard specifications with high availability, choose CD74HCT08M96 (27,700 pcs in stock).

Q: Are all substitute parts pin-compatible with 74HCT08S14-13?

A: Yes. All listed substitutes maintain identical 14-SOIC pinout and logic function. Direct board-level substitution is possible without circuit modification.

Q: What is the significance of propagation delay differences?

A: Propagation delay determines maximum operating frequency. Faster delays (17ns) support higher-speed applications. Slower delays (25ns) are acceptable for standard logic applications. Verify system timing requirements before selection.
