74VHCT00AMTC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74VHCT00AMTC is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74VHCT00 series provides standard TTL-compatible logic functionality with 4.5V to 5.5V supply voltage operation and 7.9ns maximum propagation delay at 5V with 50pF load.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74VHCT00AMTC is determined by the following critical parameters:

• Logic configuration: 4-channel 2-input NAND gate
• Supply voltage range: 4.5V ~ 5.5V minimum requirement
• Propagation delay: 7.9ns @ 5V, 50pF
• Package type: 14-TSSOP surface mount
• Input/output logic levels and current specifications
• Operating temperature range compatibility

Substitute parts are grouped into three categories:

Direct Equivalents maintain identical electrical specifications and 14-TSSOP packaging from alternative manufacturers.

Similar Parts provide the same logic function and package but with extended operating temperature ranges or wider supply voltage specifications, suitable for applications with relaxed thermal constraints.

Upgrade Parts offer the same base logic function (74AHCT00 series) with enhanced specifications, including extended temperature ranges and automotive-grade qualifications where applicable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): 74VHCT00AMTCX from Fairchild Semiconductor is the primary direct equivalent, maintaining identical electrical parameters and 14-TSSOP packaging with active product status.

For Extended Temperature Range Applications: MC74VHCT00ADTR2G from onsemi extends the operating temperature range to -55°C ~ 125°C while maintaining the 74VHCT series specifications. This part is active and available in Tape & Reel packaging.

For Automotive and Extended Temperature Requirements: SN74AHCT00QPWRG4Q1 and SN74AHCT00QPWRQ1 from Texas Instruments provide AEC-Q100 automotive qualification with extended temperature range (-40°C ~ 125°C) and active product status. Both are RoHS3 compliant.

For Standard Industrial Applications: SN74AHCT00PWR from Texas Instruments offers active product status with standard temperature range (-40°C ~ 85°C) and is RoHS3 compliant.

Package Consideration: SN74AHCT00DBR uses 14-SSOP packaging (0.209", 5.30mm Width) instead of 14-TSSOP. This represents a different physical footprint and requires PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can I use 74AHCT00 series parts as direct replacements for 74VHCT00AMTC?

A: Yes. The 74AHCT00 series maintains the same logic function (4-channel 2-input NAND gate), electrical specifications (4.5V ~ 5.5V supply, 7.9ns propagation delay), and 14-TSSOP packaging. The primary difference is the series designation, which reflects manufacturing process improvements. All electrical parameters remain compatible.

Q: What is the difference between 14-TSSOP and 14-SSOP packages?

A: 14-TSSOP (Thin Shrink Small Outline Package) has a 0.173" width (4.40mm), while 14-SSOP (Shrink Small Outline Package) has a 0.209" width (5.30mm). These are physically different packages requiring different PCB footprints. SN74AHCT00DBR uses the larger 14-SSOP package and is not a pin-compatible replacement without PCB modification.

Q: Why is the 74VHCT00AMTC marked as obsolete?

A: The original part is obsolete, but equivalent and substitute parts from multiple manufacturers remain in active production. Direct equivalents like 74VHCT00AMTCX and upgraded alternatives like the 74AHCT00 series provide continued design support.

Q: Are all substitute parts RoHS3 compliant?

A: Most active substitute parts are RoHS3 compliant. Verify RoHS status for specific part numbers in your procurement requirements, particularly for 74AHCT00PW,118 from NXP Semiconductors, which has limited specification data.

Q: What is the difference between automotive-qualified parts (AEC-Q100) and standard parts?

A: Automotive-qualified parts (SN74AHCT00QPWRG4Q1, SN74AHCT00QPWRQ1, 74AHCT00PW-Q100J) undergo additional qualification testing for automotive applications, including extended temperature cycling and reliability verification. These parts are suitable for both automotive and industrial applications.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All listed substitute parts maintain identical logic function and electrical specifications within the specified parameters. However, verify packaging type (14-TSSOP vs. 14-SSOP) and operating temperature range requirements for your specific application before mixing manufacturers.
