SN74HC74N-P2 Equivalent & Substitute Parts

Part Overview

The SN74HC74N-P2 is a dual D-type flip-flop logic integrated circuit manufactured by Texas Instruments. This device functions as a 2-element D-type flip-flop with 1-bit per element, featuring complementary outputs and positive edge triggering. The component operates across a supply voltage range of 2V to 6V and is housed in a 14-DIP (0.300", 7.62mm) through-hole package.

The SN74HC74N-P2 is classified as an Active product with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance, functional characteristics, and mechanical compatibility are maintained across the specified parameter set. Packaging variations and inventory availability may necessitate alternative part selection while preserving circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC74N-P2 is determined by strict equivalence across the following critical parameters:

Functional Parameters: Series (74HC), device type (D-Type Flip-Flop), number of elements (2), bits per element (1), output type (Complementary), and trigger type (Positive Edge) must remain identical.

Electrical Parameters: Clock frequency (60 MHz), maximum propagation delay (30 ns @ 6V, 50pF), supply voltage range (2V ~ 6V), output current ratings (5.2 mA high and low), quiescent current (4 µA), and input capacitance (3 pF) must be maintained.

Mechanical Parameters: Package type (14-DIP with 0.300", 7.62mm pitch) and mounting type (Through Hole) must be preserved.

Compliance Parameters: RoHS3 compliance and Active product status are required.

Substitute parts identified within this specification maintain 100% electrical and mechanical compatibility with the SN74HC74N-P2. Packaging format variations (such as Tube versus standard packaging) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC74N and SN74HC74N-P2 are direct parametric equivalents. Both devices are manufactured by Texas Instruments, maintain identical electrical specifications, and are housed in the same 14-DIP through-hole package. Both parts carry Active product status and full RoHS3 compliance.

The primary distinction between these parts is packaging format: the SN74HC74N-P2 uses standard packaging, while the SN74HC74N is supplied in Tube packaging. This difference does not affect electrical performance or mechanical compatibility in circuit applications.

Selection between these equivalent parts should be based on:

Inventory Availability: The SN74HC74N maintains higher inventory levels (13,752 pieces) compared to the SN74HC74N-P2 (1,030 pieces).

Packaging Requirements: Choose based on procurement and assembly process requirements. Tube packaging (SN74HC74N) is suitable for automated pick-and-place assembly, while standard packaging (SN74HC74N-P2) accommodates manual or alternative assembly methods.

Supply Chain Continuity: Both parts are Active products from the same manufacturer, ensuring long-term availability and consistent quality.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC74N be used as a direct replacement for the SN74HC74N-P2?

A: Yes. The SN74HC74N is a direct parametric equivalent. All electrical characteristics, functional specifications, and mechanical dimensions are identical. The only difference is packaging format (Tube versus standard).

Q: What does "Tube packaging" mean for the SN74HC74N?

A: Tube packaging refers to the delivery format in which components are supplied in plastic tubes, typically containing 50 or 100 units per tube. This format is optimized for automated assembly equipment. Standard packaging uses alternative delivery methods. Both formats contain identical components with identical electrical performance.

Q: Are there any compatibility issues when substituting between SN74HC74N-P2 and SN74HC74N?

A: No compatibility issues exist. Both parts are pin-compatible, electrically equivalent, and mechanically identical in the 14-DIP package. They can be used interchangeably in any circuit application.

Q: What are the critical parameters that define substitution for D-type flip-flops?

A: Critical parameters include: series designation (74HC), device type (D-Type), number of elements (2), bits per element (1), output type (Complementary), trigger type (Positive Edge), clock frequency (60 MHz), propagation delay (30 ns @ 6V, 50pF), supply voltage range (2V ~ 6V), output current (5.2 mA), quiescent current (4 µA), and package type (14-DIP through-hole).

Q: Does packaging format affect the electrical performance of these flip-flops?

A: No. Packaging format (Tube or standard) is a delivery and handling specification only. It does not affect electrical performance, timing characteristics, or functional behavior of the integrated circuit.

Q: Are both parts suitable for new designs?

A: Yes. Both the SN74HC74N-P2 and SN74HC74N are classified as Active products, indicating full manufacturer support and suitability for new design implementations.

Q: What is the operating temperature range for these devices?

A: Both parts operate across -40°C to 85°C (TA), making them suitable for industrial and commercial temperature environments.
