SN74AC00NG4 Equivalent & Substitute Parts

Part Overview

The SN74AC00NG4 is a NAND Gate IC with 4 channels and 2 inputs per channel, packaged in a 14-PDIP configuration. This Texas Instruments component operates across a 2V to 6V supply voltage range and is designed for through-hole mounting applications. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Functionally equivalent alternatives maintain the same logic architecture and pin configuration while offering active product status and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74AC00NG4 is determined by the following critical parameters:

• Logic Architecture: NAND Gate with 4 channels, 2 inputs per channel
• Package Compatibility: 14-DIP form factor with 0.300" (7.62mm) pitch
• Mounting Type: Through-hole configuration
• Supply Voltage Range: Minimum 2V operation with maximum rating of 5.5V or higher
• Output Drive Capability: 24mA minimum for both high and low states
• Operating Temperature Range: -40°C to 85°C minimum
• Compliance: ROHS3 and REACH compliance maintained

The TC74AC00PF from Toshiba Semiconductor meets all substitution criteria. Both parts share the 74AC base product number, identical logic configuration, and compatible electrical characteristics within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The TC74AC00PF is a direct functional equivalent for the SN74AC00NG4. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system maintenance.

The Toshiba TC74AC00PF offers superior performance characteristics: propagation delay is reduced to 7ns compared to 8ns in the original part, and quiescent current is specified at 4µA versus 2µA. These differences remain within acceptable operational margins for 74AC logic family applications. The supply voltage range of 2V to 5.5V in the substitute covers the critical 5V operating point and maintains compatibility with the original 2V minimum threshold.

Selection of the TC74AC00PF is appropriate for applications where the SN74AC00NG4 is no longer available. The active product status of the Toshiba component ensures continued supply chain access and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the TC74AC00PF directly replace the SN74AC00NG4 in existing PCB designs?

A: Yes. Both components use identical 14-DIP packaging with 0.300" pitch and through-hole mounting. Pin configuration and functional behavior are equivalent. No PCB layout modifications are required.

Q: What is the significance of the supply voltage difference (6V vs 5.5V)?

A: The SN74AC00NG4 specifies a maximum of 6V, while the TC74AC00PF specifies 5.5V. For applications operating at or below 5.5V, both parts are fully compatible. Applications requiring operation above 5.5V must remain with the original TI part or identify alternative solutions.

Q: Does the faster propagation delay of the TC74AC00PF affect system compatibility?

A: No. The 7ns propagation delay of the TC74AC00PF is faster than the 8ns specification of the SN74AC00NG4. Faster propagation delays do not create compatibility issues in systems designed for the original part.

Q: Are both parts suitable for new product designs?

A: The TC74AC00PF is recommended for new designs due to its active product status. The SN74AC00NG4 is discontinued and should not be specified for new development.

Q: What packaging options are available for these parts?

A: The SN74AC00NG4 is supplied in standard packaging. The TC74AC00PF is available in tube packaging. Both maintain the 14-DIP form factor and are compatible with standard through-hole assembly processes.
