CD74HC75M Equivalent & Substitute Parts

Part Overview

The CD74HC75M is a dual 2-bit transparent latch logic IC manufactured by Texas Instruments in 16-SOIC surface mount packaging. This component functions as a D-type transparent latch with 2 independent circuits and differential output configuration. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this logic function.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC75M is determined by the following critical parameters:

• Logic Function: D-Type Transparent Latch with identical circuit topology (2:2 configuration)
• Electrical Specifications: Voltage supply range (2V ~ 6V), propagation delay (10ns), output current ratings (5.2mA), and operating temperature range (-55°C ~ 125°C)
• Package Compatibility: 16-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating
• Base Product Number: 74HC75 series designation

The substitute parts listed maintain functional equivalence through identical logic type, circuit configuration, electrical performance, and package specifications. Packaging format (Tube, Tape & Reel, Bulk, Cut Tape) represents the only variable parameter and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

CD74HC75M96 (Texas Instruments, Tape & Reel packaging) is the primary direct substitute. This part maintains identical electrical specifications, package configuration, and functional characteristics as the main part. The only difference is packaging format (Tape & Reel versus Tube), which does not affect circuit performance. Product status is Active, ensuring continued availability and supply chain stability.

74HC75D,653 (NXP Semiconductors, Bulk packaging) provides functional equivalence as a 74HC75 base product number variant. This part maintains the D-Type Transparent Latch logic type and 2:2 circuit configuration. Product status is Active. Limited specification data is provided for this part; verification of electrical parameters against design requirements is necessary before implementation.

74HCT14D,653 (Nexperia USA Inc., Cut Tape & Digi-Reel packaging) is not a direct functional equivalent. This part is an Inverter IC with Schmitt Trigger configuration and 6-channel topology, differing fundamentally in logic type and circuit architecture from the CD74HC75M. Additionally, the voltage supply range (4.5V ~ 5.5V) is narrower than the main part (2V ~ 6V), and the package type is 14-SOIC rather than 16-SOIC. This part should not be selected as a substitute for applications requiring D-Type Transparent Latch functionality.

Frequently Asked Questions (FAQ)

Q: Can CD74HC75M96 be used as a direct replacement for CD74HC75M?

A: Yes. CD74HC75M96 is a direct functional and electrical equivalent. Both parts share identical logic type (D-Type Transparent Latch), circuit configuration (2:2), voltage supply range (2V ~ 6V), propagation delay (10ns), output current ratings (5.2mA), operating temperature range (-55°C ~ 125°C), and 16-SOIC package specifications. The difference in packaging format (Tape & Reel versus Tube) does not affect circuit performance or compatibility.

Q: What is the difference between CD74HC75M and CD74HC75M96?

A: The electrical and functional specifications are identical. The primary difference is packaging format: CD74HC75M is supplied in Tube packaging, while CD74HC75M96 is supplied in Tape & Reel (TR) format. Both parts are manufactured by Texas Instruments and meet ROHS3 compliance and MSL Level 1 requirements.

Q: Is 74HC75D,653 compatible with CD74HC75M?

A: 74HC75D,653 shares the same base product number (74HC75) and logic type (D-Type Transparent Latch with 2:2 circuit configuration). However, limited specification data is provided for this NXP Semiconductors part. Before implementation, verify that all electrical parameters (voltage supply range, propagation delay, output current, operating temperature) meet your design requirements.

Q: Why is 74HCT14D,653 listed as a substitute if it is not compatible?

A: 74HCT14D,653 is listed in the original substitute data but is not a functional equivalent. This part is an Inverter IC with Schmitt Trigger configuration, not a D-Type Transparent Latch. The logic type, circuit topology, package type (14-SOIC), and voltage supply range (4.5V ~ 5.5V) differ from the CD74HC75M. This part should not be selected for applications requiring D-Type Transparent Latch functionality.

Q: What packaging formats are available for 74HC75 series parts?

A: The 74HC75 base product is available in multiple packaging formats: Tube (CD74HC75M), Tape & Reel (CD74HC75M96), Bulk (74HC75D,653), and Cut Tape & Digi-Reel (other variants). Packaging format selection depends on manufacturing volume and assembly requirements but does not affect electrical performance or circuit compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CD74HC75M, CD74HC75M96, 74HC75D,653, and 74HCT14D,653 are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts meet REACH compliance requirements.
