CD74HC75MT Equivalent & Substitute Parts

Part Overview

The CD74HC75MT is a dual 2-bit transparent latch IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This D-type transparent latch operates across a 2V to 6V supply voltage range and is designed for applications requiring high-speed logic latching with differential outputs. The part is currently in Last Time Buy status, making identification of equivalent and substitute components essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC75MT is determined by strict alignment of the following critical parameters:

• Logic Function: D-Type Transparent Latch with 2:2 circuit configuration and differential output
• Electrical Specifications: Supply voltage range (2V ~ 6V), propagation delay (10ns), output current capability (5.2mA)
• Package Compatibility: 16-SOIC surface mount package with identical physical dimensions
• Environmental & Compliance: Operating temperature range (-55°C ~ 125°C), RoHS3 compliance, MSL Level 1
• Base Product Series: 74HC logic family

The identified substitute parts maintain functional and electrical equivalence within these parameters while differing in manufacturer, product status, or packaging format.

Parameter Comparison

Engineering Selection Recommendations

CD74HC75M96 is the primary parametric equivalent. This Texas Instruments part maintains identical electrical specifications, package format, and environmental ratings as the CD74HC75MT. The only distinction is active product status versus Last Time Buy, making this the preferred long-term substitute for new designs and procurement.

74HC75D,653 (NXP Semiconductors) is manufacturer-recommended as a functional equivalent within the 74HC logic family. This part shares the base product number 74HC75 and maintains RoHS3 compliance and MSL Level 1 rating. However, detailed electrical parameters are not provided in the specification data. Packaging is supplied in Bulk format rather than Tape & Reel.

74HCT14D,653 (Nexperia USA Inc.) is listed as a substitute but represents a fundamentally different logic function (Inverter with Schmitt Trigger versus D-Type Transparent Latch). This part operates within a narrower supply voltage range (4.5V ~ 5.5V), exhibits longer propagation delay (34ns), and uses a 14-SOIC package. This part is not functionally equivalent and should not be selected as a direct replacement.

Frequently Asked Questions (FAQ)

Q: Can CD74HC75M96 be used as a direct replacement for CD74HC75MT?

A: Yes. CD74HC75M96 maintains identical electrical specifications, package dimensions, and environmental operating parameters. Both parts are 16-SOIC surface mount devices with 2V to 6V supply voltage, 10ns propagation delay, and 5.2mA output current capability. The primary difference is product status (Active versus Last Time Buy).

Q: Is 74HC75D,653 from NXP a suitable substitute?

A: 74HC75D,653 shares the base product number 74HC75 and is manufacturer-recommended as a functional equivalent. However, complete electrical parameter specifications are not provided in available data. Verification of electrical compatibility with your specific application is necessary before selection. This part is supplied in Bulk packaging rather than Tape & Reel format.

Q: Why is 74HCT14D,653 listed as a substitute if it is functionally different?

A: 74HCT14D,653 is an Inverter with Schmitt Trigger function, not a D-Type Transparent Latch. This part operates within a restricted supply voltage range (4.5V ~ 5.5V versus 2V ~ 6V), has longer propagation delay (34ns versus 10ns), and uses a different package (14-SOIC versus 16-SOIC). This part is not functionally equivalent and is not suitable as a direct replacement.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) identical logic function (D-Type Transparent Latch), (2) matching circuit configuration (2:2 channels with differential output), (3) compatible supply voltage range (2V ~ 6V), (4) equivalent propagation delay (10ns), (5) matching output current capability (5.2mA), (6) identical package format (16-SOIC), and (7) compliance certifications (RoHS3, MSL Level 1).

Q: Does packaging format affect substitution?

A: Packaging format (Tape & Reel, Bulk, Cut Tape) does not affect electrical or functional compatibility. However, it impacts procurement logistics, handling, and assembly processes. CD74HC75M96 and CD74HC75MT both use Tape & Reel format, while 74HC75D,653 uses Bulk packaging. Verify your assembly process requirements before selecting based on packaging format.

Q: What is the significance of Last Time Buy status for CD74HC75MT?

A: Last Time Buy status indicates that Texas Instruments will discontinue this part number. Existing inventory may be available for a limited period, but long-term availability is not guaranteed. CD74HC75M96 (Active status) is recommended for new designs and future procurement to ensure supply continuity.
