Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LV174ADE4 is determined by strict equivalence across the following critical parameters:

• Functional Architecture: D-Type flip-flop with 1 element, 6 bits per element, positive edge triggering, and non-inverted output
• Electrical Performance: Clock frequency of 180 MHz, propagation delay of 9.2 ns @ 5V/50pF, output current capability of 12 mA, supply voltage range of 2V ~ 5.5V
• Package Specification: 16-SOIC surface mount package with 0.154" (3.90mm) width
• Environmental & Compliance: Operating temperature range -40°C ~ 85°C, ROHS3 compliance, MSL Level 1, REACH unaffected status

The substitute part SN74LV174AD meets all these criteria with identical electrical and functional specifications, differing only in packaging format (Tube vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The SN74LV174AD serves as a direct functional and electrical equivalent to the SN74LV174ADE4. Both parts are manufactured by Texas Instruments under the 74LV series base product number and maintain identical specifications across all critical parameters. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance differences.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The MSL Level 1 rating indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can SN74LV174AD be used as a direct replacement for SN74LV174ADE4?

A: Yes. Both parts are electrically and functionally identical, with specifications matching across all parameters including clock frequency, propagation delay, output current, supply voltage range, and operating temperature. The difference lies in packaging format only.

Q: What is the difference between SN74LV174ADE4 and SN74LV174AD?

A: The primary difference is packaging format. SN74LV174ADE4 uses standard packaging, while SN74LV174AD is supplied in Tube packaging. Both use the identical 16-SOIC surface mount package with 0.154" width.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts share the same pinout, electrical characteristics, and package dimensions. PCB layout and circuit design remain unchanged.

Q: What does the 74LV designation indicate?

A: The 74LV prefix indicates a low-voltage logic family from Texas Instruments, operating within the 2V ~ 5.5V supply voltage range with reduced power consumption compared to standard 74-series logic.

Q: Is the 16-SOIC package suitable for automated assembly?

A: Yes. The 16-SOIC surface mount package is standard for automated pick-and-place assembly and reflow soldering processes.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 indicates unlimited shelf life under standard storage conditions (typically 30°C/85% RH). No moisture baking is required before soldering.
