SN74LVC08APWR-P Equivalent & Substitute Parts

Part Overview

The SN74LVC08APWR-P is a 4-channel 2-input AND Gate logic integrated circuit manufactured by Texas Instruments in the 74LVC series. This device operates across a supply voltage range of 1.65V to 3.6V and is housed in a 14-TSSOP surface mount package. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative packaging formats and quiescent current variations within the same logic family enable component selection flexibility for procurement, inventory, and application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC08APWR-P is determined by strict equivalence across the following critical parameters:

Functional Parameters: Logic type (AND Gate), number of circuits (4), and number of inputs (2) must remain identical.

Electrical Parameters: Supply voltage range (1.65V ~ 3.6V), output current capability (24mA high and low), input logic thresholds (0.7V ~ 0.8V low; 1.7V ~ 2V high), and propagation delay (3.9ns @ 3.3V, 50pF) must be maintained.

Mechanical Parameters: Package type (14-TSSOP) and mounting method (Surface Mount) must be identical.

Compliance Parameters: RoHS3 compliance and MSL Level 1 rating must be present.

The identified substitute parts SN74LVC08APWRG3 and SN74LVC08APW differ only in packaging format (Tape & Reel and Tube, respectively) while maintaining all electrical and functional specifications. Quiescent current variation (1 µA vs. 10 µA) does not disqualify substitution as this parameter was not specified as a selection criterion for the main part.

Engineering Selection Recommendations

All three parts maintain Active product status from Texas Instruments and carry ROHS3 compliance with MSL Level 1 rating, confirming suitability for current and future production environments.

SN74LVC08APWRG3 is supplied in Tape & Reel format, appropriate for high-volume automated assembly operations where continuous reel feeding is standard.

SN74LVC08APW is supplied in Tube packaging, suitable for lower-volume applications, manual assembly processes, or component kitting workflows.

Selection between substitute parts depends on assembly methodology and procurement volume requirements rather than electrical or functional differences. All three parts deliver identical logic performance and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC08APWRG3 replace SN74LVC08APWR-P in production?

A: Yes. Both parts are electrically and functionally identical across all specified parameters. The difference is packaging format: Tape & Reel versus Tube. Selection depends on assembly equipment compatibility and procurement volume.

Q: What is the significance of the quiescent current difference (10 µA vs. 1 µA)?

A: The quiescent current specification was not provided as a selection criterion for the main part. Both values fall within acceptable ranges for 74LVC logic family operation. This parameter does not disqualify substitution.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-TSSOP package with identical pinout, mechanical dimensions (0.173" width, 4.40mm), and surface mount configuration.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. SN74LVC08APWRG3 and SN74LVC08APW both carry ROHS3 compliance, MSL Level 1 rating, and Active product status identical to the main part.

Q: Which substitute should be selected for high-volume manufacturing?

A: SN74LVC08APWRG3 in Tape & Reel format is optimized for automated pick-and-place assembly. SN74LVC08APW in Tube format is suitable for lower-volume or manual assembly processes.

Q: Are there any thermal or operating condition differences between the parts?

A: No. All three parts operate across the identical temperature range (-40°C ~ 125°C) and maintain the same propagation delay specification (3.9ns @ 3.3V, 50pF).
