CD74HCT11MT AND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HCT11MT is a 3-channel AND gate logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The CD74HCT11MT operates within the 74HCT logic family standard, which ensures functional compatibility with qualified alternative sources from other manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HCT11MT is determined by strict equivalence across the following critical parameters: logic type (AND gate), circuit count (3 channels), input count (3 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (4mA high and low), input logic thresholds (0.8V low, 2V high), and package type (14-SOIC surface mount). All qualified substitutes maintain these electrical characteristics and physical form factor. Propagation delay and operating temperature range may vary within acceptable limits for the 74HCT logic family standard. Packaging format (Cut Tape, Tape & Reel, or Bulk) does not affect functional equivalence but impacts procurement and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT11M96 is the primary parametric equivalent from Texas Instruments, maintaining identical electrical specifications and operating temperature range (-55°C ~ 125°C) with active product status and full ROHS3 compliance. This part is the direct successor for applications requiring the extended temperature range of the discontinued CD74HCT11MT.

74HCT11D,652 from NXP Semiconductors is functionally equivalent across all critical electrical parameters. This part is available in bulk packaging and maintains active status. Specific operating temperature and propagation delay data are not provided in the available documentation.

74HCT11D,653 from Nexperia USA Inc. is functionally equivalent with active product status and ROHS3 compliance. This part operates within a narrower temperature range (-40°C ~ 125°C) compared to the original CD74HCT11MT (-55°C ~ 125°C) and features slightly faster propagation delay (24ns versus 28ns). Selection is appropriate for applications not requiring extended low-temperature operation below -40°C.

74HCT11D-Q100J from Nexperia USA Inc. is functionally equivalent with automotive-grade qualification (AEC-Q100) and active product status. This part operates within the -40°C ~ 125°C temperature range and is suitable for automotive applications requiring qualified components. ROHS3 compliance and MSL rating 1 are maintained.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT11M96 directly replace CD74HCT11MT in all applications?

A: Yes. CD74HCT11M96 maintains identical electrical specifications, supply voltage range, output current ratings, input logic thresholds, and operating temperature range (-55°C ~ 125°C). Both parts are 14-SOIC surface mount packages with equivalent pinout and functional behavior.

Q: What is the difference between 74HCT11D,653 and CD74HCT11MT?

A: Both parts are functionally equivalent AND gates with identical logic specifications. The primary differences are: 74HCT11D,653 operates at -40°C ~ 125°C (versus -55°C ~ 125°C for CD74HCT11MT), features faster propagation delay (24ns versus 28ns), and is manufactured by Nexperia USA Inc. rather than Texas Instruments. Selection depends on whether the application requires operation below -40°C.

Q: Is 74HCT11D-Q100J suitable for non-automotive applications?

A: Yes. 74HCT11D-Q100J meets all electrical and mechanical requirements for standard logic applications. The AEC-Q100 automotive qualification is an additional certification that does not restrict use in non-automotive designs. This part is functionally equivalent to all other substitutes listed.

Q: What packaging formats are available for these substitutes?

A: CD74HCT11M96 is available in Cut Tape (CT) & Digi-Reel format. 74HCT11D,652 is available in Bulk packaging. 74HCT11D,653 and 74HCT11D-Q100J are available in Tape & Reel (TR) format. All parts use identical 14-SOIC surface mount packages.

Q: Are all substitutes ROHS3 compliant?

A: CD74HCT11M96, 74HCT11D,653, and 74HCT11D-Q100J are confirmed ROHS3 compliant. ROHS3 compliance status for 74HCT11D,652 is not specified in available documentation.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All listed substitutes share identical pinout, 14-SOIC package dimensions (0.154", 3.90mm width), and electrical characteristics. PCB layout and footprints designed for CD74HCT11MT are compatible with all substitute parts without modification.
