Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC75DB,118 is determined by the following critical parameters:

Functional Equivalence Requirements:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2:2 (2 Channel)
• Output Type: Differential
• Independent Circuits: 2

Electrical Compatibility Requirements:

• Supply Voltage Range: 2V ~ 6V
• Output Current: 5.2mA (High and Low)
• Propagation Delay: 11ns (maximum acceptable)

Physical and Environmental Requirements:

• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts must maintain identical functional specifications and electrical parameters. Package variations (16-SSOP vs. 16-TSSOP) are acceptable provided the pin configuration and footprint compatibility are verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CD74HC75PWR

CD74HC75PWR is the recommended substitute for the 74HC75DB,118. This Texas Instruments part maintains full functional and electrical equivalence with active product status, ensuring long-term availability and supply chain stability. The part is ROHS3 compliant and REACH unaffected, meeting all regulatory requirements. The 16-TSSOP package is functionally compatible with the original 16-SSOP package for surface mount applications.

Secondary Substitute: 74HC75PW,118

74HC75PW,118 from NXP Semiconductors provides an alternative with active product status. This part is supplied in bulk packaging and maintains electrical equivalence to the original component.

Tertiary Substitutes: CD74HC75PW and CD74HC75PWT

CD74HC75PW and CD74HC75PWT are functionally equivalent alternatives from Texas Instruments. CD74HC75PW is supplied in tube packaging, while CD74HC75PWT is supplied in tape and reel format. Both parts are classified as Last Time Buy, indicating limited future availability.

All substitute parts meet ROHS3 compliance and REACH requirements. Selection should prioritize parts with active product status for new designs and long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74HC75DB,118 be directly replaced with CD74HC75PWR?

A: Yes. Both parts share identical functional specifications (D-Type Transparent Latch, 2:2 configuration, differential output), electrical parameters (2V ~ 6V supply, 5.2mA output current), and environmental ratings (MSL 1, ROHS3 compliant). The package change from 16-SSOP to 16-TSSOP requires PCB footprint verification but does not affect electrical compatibility.

Q: What is the difference between 16-SSOP and 16-TSSOP packages?

A: Both are 16-pin surface mount packages with different physical dimensions. 16-SSOP has a width of 0.209" (5.30mm), while 16-TSSOP has a width of 0.173" (4.40mm). Pin pitch and electrical characteristics remain compatible. PCB layout must accommodate the specific package footprint selected.

Q: Why is the 74HC75DB,118 classified as obsolete?

A: The original part has reached end-of-life status. Active substitute parts such as CD74HC75PWR provide equivalent functionality with ongoing manufacturer support and availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (74HC75PW,118, CD74HC75PW, CD74HC75PWR, CD74HC75PWT) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the propagation delay difference between the main part and substitutes?

A: The 74HC75DB,118 specifies 11ns propagation delay. Texas Instruments substitutes (CD74HC75PW, CD74HC75PWR, CD74HC75PWT) specify 10ns, which is faster and maintains backward compatibility. The 74HC75PW,118 does not specify propagation delay in the provided data.

Q: Which substitute should be selected for new designs?

A: CD74HC75PWR is recommended for new designs due to active product status, ensuring long-term availability and supply chain continuity. This part is available in tape and reel packaging suitable for automated assembly processes.
