Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74AHC08N-P2 are identified based on strict parametric equivalence. The critical parameters determining substitution eligibility are:

Logic Function: AND Gate with 4 circuits and 2 inputs per circuit

Electrical Specifications: Supply voltage range 2V ~ 5.5V, quiescent current 2 µA maximum, output current 8mA for both high and low states, propagation delay 7.9ns at 5V with 50pF load

Mechanical Compatibility: 14-DIP package with 0.300" (7.62mm) pitch, through-hole mounting

Compliance Requirements: ROHS3 compliance and Active product status

Manufacturer: Texas Instruments

Parts meeting all these parameters are classified as parametric equivalents and may be substituted without circuit redesign or functional impact.

Parameter Comparison

Engineering Selection Recommendations

The SN74AHC08N and SN74AHC08N-P2 are parametric equivalents from Texas Instruments. Both parts maintain identical electrical characteristics, operating ranges, and mechanical specifications. The primary distinction is packaging format: SN74AHC08N-P2 is supplied in tape-and-reel format, while SN74AHC08N is supplied in tube packaging.

Both parts carry Active product status, confirming ongoing manufacturer support and availability. Both achieve ROHS3 compliance, meeting environmental and regulatory requirements for modern electronics manufacturing.

Selection between these equivalents should be based on procurement requirements and supply chain logistics. Tape-and-reel packaging (SN74AHC08N-P2) is optimized for automated assembly processes, while tube packaging (SN74AHC08N) is suitable for manual assembly or lower-volume applications. Electrical and functional performance remains identical across both packaging options.

Frequently Asked Questions (FAQ)

Q: Can SN74AHC08N be used as a direct replacement for SN74AHC08N-P2?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, logic function, and package dimensions. The difference is packaging format only: tape-and-reel versus tube. Functional performance and circuit compatibility are equivalent.

Q: What is the difference between tape-and-reel and tube packaging?

A: Tape-and-reel packaging (SN74AHC08N-P2) is designed for automated pick-and-place assembly equipment. Tube packaging (SN74AHC08N) is designed for manual handling and lower-volume assembly. Both contain the same die and deliver identical electrical performance.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SN74AHC08N-P2 and SN74AHC08N meet ROHS3 compliance requirements, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: What are the critical parameters for AND gate substitution?

A: Critical parameters include logic function (AND gate), number of circuits (4), inputs per circuit (2), supply voltage range (2V ~ 5.5V), output current capability (8mA), propagation delay (7.9ns at 5V, 50pF), and package type (14-DIP through-hole). All parameters must match for functional equivalence.

Q: Can these parts operate at different supply voltages?

A: Both parts operate across the specified range of 2V to 5.5V. Input and output logic levels adjust according to the applied supply voltage within this range. Consult the datasheet for specific logic level thresholds at your operating voltage.

Q: What is the operating temperature range?

A: Both parts operate from -40°C to 125°C. This range covers industrial and commercial temperature environments. Verify your application's temperature requirements fall within this specification.
