SN74LV08ATPWREP Equivalent & Substitute Parts

Part Overview

The SN74LV08ATPWREP is a 4-channel 2-input AND gate logic IC manufactured by Texas Instruments, housed in a 14-TSSOP surface mount package. This component operates across a 2V to 5.5V supply voltage range and is designed for low-voltage digital logic applications. The part is currently active in production with 795 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers offer improved inventory levels, or when design requirements necessitate different electrical characteristics such as extended temperature ranges or modified quiescent current specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LV08ATPWREP is determined by the following critical parameters:

Logic Type: AND Gate (4 channels, 2 inputs per channel)
Package Type: 14-TSSOP surface mount configuration
Supply Voltage Range: Minimum 2V support required
Output Drive Capability: 12mA minimum for both high and low states
Propagation Delay: Maximum 7.9ns at 5V with 50pF load
Operating Temperature: Minimum -40°C to 105°C range
RoHS3 Compliance: Required for environmental standards

Parts are grouped into three categories based on their relationship to the main part: parametric equivalents (identical electrical specifications), upgrades (extended temperature or automotive qualification), and manufacturer-recommended alternatives (different manufacturers with comparable performance).

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement)

SN74LV08ATPWRG4Q1 from Texas Instruments is a parametric equivalent with identical electrical specifications. This part includes AEC-Q100 automotive qualification and is suitable for applications requiring automotive-grade components. Inventory availability is significantly higher at 8,300 units.

Extended Temperature Range Alternative

74LV08AT14-13 from Diodes Incorporated maintains all electrical parameters of the main part while extending the operating temperature range to -40°C to 125°C. This part is recommended for applications requiring enhanced thermal performance. Inventory level is 44,228 units.

Manufacturer-Recommended Alternatives

74LV08PW,118 from Nexperia USA Inc. extends the supply voltage range to 1V minimum and provides an operating temperature range of -40°C to 125°C. Quiescent current is specified at 40 µA maximum. This part is suitable for low-voltage applications.

MC74LVX08DTR2G and MC74LVX08MTCX from onsemi represent the 74LVX series with reduced quiescent current (2 µA) and lower output drive capability (4mA). These parts are restricted to 2V to 3.6V supply voltage and -40°C to 85°C operating temperature. Selection of these parts requires verification that the reduced output drive current and narrower voltage range are compatible with the target application.

MC74LVX08DR2G from onsemi is functionally equivalent to MC74LVX08DTR2G but uses a 14-SOIC package instead of 14-TSSOP. Package selection depends on PCB layout requirements.

MC74LVX08DTG from onsemi is obsolete and should not be selected for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can SN74LV08ATPWRG4Q1 be used as a direct replacement for SN74LV08ATPWREP?

A: Yes. SN74LV08ATPWRG4Q1 is a parametric equivalent with identical electrical specifications, supply voltage range, output drive capability, and operating temperature range. The primary difference is automotive qualification (AEC-Q100), which adds value for automotive applications without affecting general-purpose logic functionality.

Q: What is the key difference between the 74LV series and 74LVX series substitutes?

A: The 74LVX series (MC74LVX08DTR2G, MC74LVX08MTCX) operates at reduced quiescent current (2 µA vs. 20 µA) but with lower output drive capability (4mA vs. 12mA) and a narrower supply voltage range (2V to 3.6V vs. 2V to 5.5V). Selection requires verification that the application can tolerate reduced output current and does not require 5V operation.

Q: Is MC74LVX08DR2G compatible with the original part?

A: MC74LVX08DR2G is electrically equivalent to MC74LVX08DTR2G but uses a 14-SOIC package instead of 14-TSSOP. It is not a direct replacement for SN74LV08ATPWREP due to package incompatibility and the electrical differences noted above. Package selection depends on PCB design requirements.

Q: Why is MC74LVX08DTG listed as obsolete?

A: MC74LVX08DTG is marked as obsolete by the manufacturer. New designs should not incorporate this part. Existing designs using this part should transition to MC74LVX08DTR2G or another active alternative.

Q: Can 74LV08PW,118 from Nexperia be used in place of the Texas Instruments part?

A: 74LV08PW,118 maintains the core AND gate functionality and 14-TSSOP package but differs in quiescent current specification (40 µA vs. 20 µA) and propagation delay measurement conditions (9ns @ 3.3V vs. 7.9ns @ 5V). It extends the supply voltage range to 1V and operating temperature to 125°C. Compatibility depends on whether the application can tolerate the increased quiescent current and different propagation delay characteristics.

Q: What parameters must remain constant for a part to be considered a substitute?

A: The following parameters must be maintained: logic type (AND gate), number of circuits (4), number of inputs per circuit (2), package type (14-TSSOP for direct PCB replacement), and minimum supply voltage support (2V). Output drive capability and propagation delay must meet or exceed the original specifications for the application.
