Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC75PWT is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2:2 (2 independent circuits)
• Output Type: Differential
• Voltage Supply Range: 2V ~ 6V
• Propagation Delay: 10ns
• Output Current Capability: 5.2mA (High and Low)
• Operating Temperature Range: -55°C ~ 125°C
• Package Type: 16-TSSOP surface mount
• Pin Configuration: Identical pinout required

Substitute parts must maintain identical electrical performance, thermal characteristics, and physical package dimensions to ensure direct replacement without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

CD74HC75PWR (Parametric Equivalent - Texas Instruments)

The CD74HC75PWR is a direct parametric equivalent to the CD74HC75PWT, manufactured by Texas Instruments with identical electrical specifications and package configuration. This part maintains Active product status, ensuring long-term availability and supply chain continuity. With 2200 units in stock and full ROHS3 compliance, the CD74HC75PWR is the primary substitute for applications requiring Texas Instruments sourcing or existing supply agreements with this manufacturer.

74HC75PW,118 (MFR Recommended - NXP Semiconductors)

The 74HC75PW,118 is the manufacturer-recommended alternative from NXP Semiconductors, based on the 74HC75 base product number. This part maintains Active product status with the highest available inventory (7264 units). The bulk packaging format differs from the tape & reel configuration of the main part, requiring evaluation of procurement and assembly processes. This option provides maximum supply availability and represents the cross-manufacturer equivalent within the 74HC logic family.

Frequently Asked Questions (FAQ)

Q: Can CD74HC75PWR be used as a direct replacement for CD74HC75PWT?

A: Yes. The CD74HC75PWR is a parametric equivalent with identical logic type, circuit configuration, output type, voltage supply range, propagation delay, output current capability, operating temperature range, and 16-TSSOP package. Direct substitution is supported without circuit modification.

Q: What is the difference between CD74HC75PWT and CD74HC75PWR?

A: Both parts are manufactured by Texas Instruments with identical electrical and mechanical specifications. The primary difference is product status: CD74HC75PWT is Last Time Buy, while CD74HC75PWR is Active. The PWR variant ensures continued availability for new designs and ongoing production.

Q: Is 74HC75PW,118 from NXP Semiconductors compatible with CD74HC75PWT?

A: The 74HC75PW,118 shares the same base product number (74HC75) and logic family. Compatibility is based on the 74HC logic family standard. However, complete electrical parameter specifications for the NXP part are not provided in this reference. Verification against the NXP datasheet is required before implementation in new designs.

Q: What packaging differences exist between these parts?

A: CD74HC75PWT and CD74HC75PWR are supplied in Tape & Reel (TR) packaging. The 74HC75PW,118 is supplied in Bulk packaging. Tape & Reel format is standard for automated assembly, while Bulk packaging requires manual handling and may impact assembly process compatibility.

Q: Are all three parts RoHS compliant?

A: CD74HC75PWT and CD74HC75PWR are confirmed ROHS3 compliant. RoHS compliance status for 74HC75PW,118 is not specified in the provided data.

Q: Which part should be selected for new designs?

A: For new designs, CD74HC75PWR is recommended due to Active product status, identical specifications to the main part, and assured long-term availability. The 74HC75PW,118 provides an alternative with higher inventory levels if cross-manufacturer sourcing is acceptable.
