74HC08T14-13 AND Gate IC Equivalent & Substitute Parts

Part Overview

The 74HC08T14-13 is a 4-channel 2-input AND gate logic IC manufactured by Diodes Incorporated in 14-TSSOP surface mount packaging. This part operates across a 2V to 6V supply voltage range with a maximum propagation delay of 15ns at 6V with 50pF load. The device is currently active in production with 22,600 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when sourcing from different manufacturers is preferred for supply chain optimization. The 74HC08 logic family maintains functional equivalence across multiple manufacturers, allowing direct substitution when electrical and mechanical parameters align.

Substitute Part Grouping Explanation

Substitution of 74HC08 AND gate ICs is determined by the following critical parameters:

Functional Parameters: Logic type (AND gate), number of circuits (4), and number of inputs per circuit (2) must remain constant across all substitutes.

Electrical Parameters: Supply voltage range, quiescent current, output current capabilities, input logic levels, and propagation delay determine functional compatibility. Parts with overlapping or superior electrical specifications within the 2V to 6V supply range are considered direct substitutes.

Mechanical Parameters: All substitute parts must use the 14-TSSOP package format with identical pin configuration and 0.173" width (4.40mm) to ensure PCB compatibility without layout modifications.

Environmental Parameters: Operating temperature range, RoHS compliance, and moisture sensitivity level must meet or exceed the application requirements.

Packaging Format: While the base product uses Tape & Reel (TR) packaging, substitutes in Cut Tape (CT), Digi-Reel, or Tube formats are electrically equivalent and differ only in supply format.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

MC74HC08ADTR2G and CD74HC08PWR are the preferred substitutes. MC74HC08ADTR2G offers superior quiescent current performance (1 µA) and faster propagation delay (13ns), with extended operating temperature range to -55°C. CD74HC08PWR matches the original propagation delay specification (15ns) while maintaining the full -55°C to 125°C temperature range. Both are currently in active production with substantial inventory availability.

Secondary Substitutes (Active Status):

SN74HC08PWR, SN74HC08IPWRG4Q1, and SN74HC08IPWRQ1 are active alternatives from Texas Instruments. These parts meet the core electrical specifications with 17ns propagation delay and operate across -40°C to 85°C. The automotive-qualified variants (SN74HC08IPWRG4Q1 and SN74HC08IPWRQ1) include AEC-Q100 certification for applications requiring automotive-grade components.

Discontinued Parts (Not Recommended for New Designs):

CD74HC08PW, SN74HC08PW, and SN74HC08PWT are discontinued at DiGi Electronics and should not be selected for new production designs. Existing inventory may be available through alternative distributors but long-term supply cannot be assured.

Obsolete Parts (Not Recommended):

NLV74HC08ADTR2G is marked obsolete and should not be used for new applications.

Packaging Considerations:

The original 74HC08T14-13 uses Tape & Reel (TR) packaging. Substitutes in Cut Tape (CT) & Digi-Reel or Tube formats are electrically identical but differ in supply format. Selection should align with assembly line requirements and minimum order quantities.

Frequently Asked Questions (FAQ)

Q: Can I substitute MC74HC08ADTR2G for 74HC08T14-13 in my design?

A: Yes. MC74HC08ADTR2G is a direct functional substitute. It maintains the same 4-channel 2-input AND gate configuration, 14-TSSOP package, and operates within the 2V to 6V supply range. The substitute offers improved quiescent current (1 µA vs. 20 µA) and faster propagation delay (13ns vs. 15ns), making it suitable for applications with tighter timing requirements or lower power budgets.

Q: What is the difference between the various Texas Instruments 74HC08 variants?

A: Texas Instruments offers multiple 74HC08 variants with differences in packaging format and operating temperature range. CD74HC08PWR and CD74HC08PW both support -55°C to 125°C operation. SN74HC08PWR, SN74HC08PW, and SN74HC08PWT operate across -40°C to 85°C. The SN74HC08IPWRG4Q1 and SN74HC08IPWRQ1 variants include automotive AEC-Q100 qualification. All variants maintain identical electrical performance within their respective temperature ranges.

Q: Are the automotive-qualified parts (SN74HC08IPWRG4Q1, SN74HC08IPWRQ1) compatible with non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed standard commercial specifications and are fully compatible with non-automotive applications. The AEC-Q100 qualification indicates additional testing and quality assurance but does not restrict use in other applications.

Q: What does the quiescent current specification mean for my application?

A: Quiescent current is the current consumed by the IC when no outputs are switching. The 74HC08T14-13 specifies 20 µA maximum, while MC74HC08ADTR2G specifies 1 µA maximum. For battery-powered or low-power applications, the lower quiescent current of MC74HC08ADTR2G reduces standby power consumption. For standard applications, both specifications are acceptable.

Q: Can I use a part with a narrower operating temperature range?

A: Only if your application operates within that narrower range. The 74HC08T14-13 operates from -40°C to 125°C. Substitutes with -40°C to 85°C range (SN74HC08PWR, SN74HC08PW, SN74HC08PWT, SN74HC08IPWRG4Q1, SN74HC08IPWRQ1) are suitable only for applications not exceeding 85°C. For full temperature range compatibility, select MC74HC08ADTR2G, CD74HC08PWR, or CD74HC08PW, which support -55°C to 125°C operation.

Q: What is the significance of the propagation delay specification?

A: Propagation delay (15ns to 20ns at 6V with 50pF load) determines the maximum speed at which the AND gate responds to input changes. For most standard logic applications, all listed substitutes meet timing requirements. Applications with critical timing constraints should select parts with lower propagation delay, such as MC74HC08ADTR2G (13ns).

Q: Are all these parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
