SN74HC374NE4 Equivalent & Substitute Parts

Part Overview

The SN74HC374NE4 is a D-Type flip-flop logic integrated circuit manufactured by Texas Instruments, classified as a standard 8-bit positive edge-triggered device in the 74HC series. This component functions as a single-element octal latch with tri-state, non-inverted outputs, housed in a 20-DIP (0.300", 7.62mm) through-hole package. The device is Active status and ROHS3 compliant, making it suitable for modern electronic applications requiring edge-triggered data storage and output control. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and functional equivalence within the 74HC logic family.

Substitute Part Grouping Explanation

Substitute parts for the SN74HC374NE4 are determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• D-Type flip-flop architecture with 8-bit configuration
• Tri-state, non-inverted output configuration
• Positive edge trigger mechanism
• 70 MHz clock frequency capability
• Supply voltage range: 2V ~ 6V
• Operating temperature range: -40°C ~ 85°C

Mechanical Compatibility Criteria:

• 20-DIP (0.300", 7.62mm) package footprint
• Through-hole mounting type
• Identical pin configuration

Compliance & Status Criteria:

• Active product status
• ROHS3 compliance
• Texas Instruments manufacturer origin

The SN74HC374N and SN74HC374AN are identified as parametric equivalents within the 74HC374 base product family. Both devices maintain identical functional specifications, package geometry, and compliance certifications as the SN74HC374NE4, differing only in packaging tube designation and minor propagation delay specifications under specific load conditions.

Parameter Comparison

Engineering Selection Recommendations

SN74HC374N Selection: The SN74HC374N is a direct parametric equivalent to the SN74HC374NE4. Both devices share identical electrical specifications, including propagation delay (39ns @ 6V, 150pF), output current ratings, and supply voltage range. The SN74HC374N maintains Active product status and ROHS3 compliance. Selection of this substitute is appropriate when inventory availability or supply chain considerations favor this variant, with no functional or performance trade-offs relative to the primary part number.

SN74HC374AN Selection: The SN74HC374AN is functionally equivalent to the SN74HC374NE4 across all critical parameters. This variant exhibits improved propagation delay performance (31ns @ 6V, 50pF) compared to the primary part, indicating faster switching characteristics under specified load conditions. The SN74HC374AN maintains identical supply voltage range, output current ratings, operating temperature range, and compliance certifications. Selection of this substitute is appropriate when improved timing performance is beneficial or when supply chain conditions favor this variant.

Compliance & Regulatory Basis: All three part numbers maintain Active product status, ROHS3 compliance, REACH Unaffected designation, and EAR99 export classification. Selection among these equivalents is based on availability, inventory levels, and application-specific timing requirements rather than regulatory or compliance constraints.

Frequently Asked Questions (FAQ)

Q: Are SN74HC374N and SN74HC374AN direct pin-for-pin replacements for SN74HC374NE4?

A: Yes. All three part numbers utilize the identical 20-DIP (0.300", 7.62mm) package with through-hole mounting. Pin configuration, functional behavior, and electrical interface are identical across all variants. Direct substitution is supported without circuit modification.

Q: What is the difference between SN74HC374NE4 and SN74HC374AN in terms of performance?

A: The primary difference is propagation delay specification. SN74HC374NE4 specifies 39ns @ 6V with 150pF load, while SN74HC374AN specifies 31ns @ 6V with 50pF load. The SN74HC374AN demonstrates faster switching response under lighter load conditions. All other electrical parameters, including supply voltage range, output current, quiescent current, and operating temperature, are identical.

Q: Can I use SN74HC374AN as a substitute if my application requires the 150pF load specification?

A: The SN74HC374AN propagation delay is specified at 50pF load, which differs from the SN74HC374NE4 specification at 150pF load. For applications with specific load requirements at 150pF, the SN74HC374N or SN74HC374NE4 are the appropriate selections. The SN74HC374AN is suitable for applications operating at or below 50pF load conditions.

Q: Are all three parts ROHS3 compliant?

A: Yes. SN74HC374NE4, SN74HC374N, and SN74HC374AN are all ROHS3 compliant and REACH Unaffected. All three variants meet current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the inventory status of these substitute parts?

A: Inventory levels are provided as reference data: SN74HC374NE4 (823 Pcs), SN74HC374N (3260 Pcs), and SN74HC374AN (3020 Pcs). Availability may vary based on current supply conditions and procurement timing.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of load specifications. All three parts are functionally equivalent D-Type 8-bit flip-flops with identical pin configuration, package geometry, and core electrical characteristics. Selection among variants should be based on propagation delay requirements relative to circuit load conditions and current inventory availability.
