74ACT00PC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACT00PC is a NAND Gate IC featuring 4 channels with 2 inputs per channel in a 14-MDIP package, manufactured by onsemi. This logic component operates within the 4.5V to 5.5V supply voltage range and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ACT00PC are qualified based on the following criteria:

Functional Equivalence: All substitute parts maintain identical logic type (NAND Gate), circuit count (4 channels), and input configuration (2 inputs per channel).

Electrical Compatibility: Supply voltage range (4.5V ~ 5.5V), output current specifications (24mA high and low), and input logic levels (0.8V low, 2V high) are matched across all qualified substitutes.

Mechanical Compatibility: All substitute parts use Through Hole mounting with 14-DIP package format (0.300", 7.62mm), ensuring direct PCB footprint compatibility.

Performance Parameters: Propagation delay and quiescent current specifications determine substitution suitability. Parts with equivalent or superior performance characteristics within the 74ACT series are included.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74ACT00N or SN74ACT00NE4 (Texas Instruments)

Both Texas Instruments parts are classified as Active products, ensuring long-term availability and supply chain stability. These parts maintain identical electrical and mechanical specifications to the 74ACT00PC while offering ROHS3 compliance. The propagation delay of 9ns matches the original specification exactly. Current inventory levels (2189 Pcs for SN74ACT00N and 714 Pcs for SN74ACT00NE4) support immediate procurement.

Secondary Recommendation: CD74ACT00E (Harris Corporation)

The CD74ACT00E provides functional equivalence with identical package and mounting specifications. However, this part is also classified as obsolete and exhibits higher quiescent current (4 µA versus 2 µA) and longer propagation delay (13.2ns versus 9ns). RoHS non-compliance status may restrict use in regulated applications. This option is suitable only when active alternatives are unavailable.

Frequently Asked Questions (FAQ)

Q: Can the SN74ACT00N directly replace the 74ACT00PC without PCB modifications?

A: Yes. Both parts use identical 14-DIP (0.300", 7.62mm) Through Hole packages with matching pin configurations. Direct socket substitution is possible without PCB layout changes.

Q: What is the significance of the propagation delay difference between the 74ACT00PC (9ns) and CD74ACT00E (13.2ns)?

A: The CD74ACT00E exhibits 4.2ns longer propagation delay. In timing-critical applications operating near maximum frequency specifications, this difference may affect circuit performance. The Texas Instruments alternatives maintain the original 9ns specification.

Q: Are the Texas Instruments parts (SN74ACT00N and SN74ACT00NE4) functionally identical?

A: Yes. Both parts share identical electrical specifications, operating temperature range, and propagation delay. The primary distinction is inventory availability (SN74ACT00N: 2189 Pcs; SN74ACT00NE4: 714 Pcs).

Q: Why is RoHS compliance status relevant for this logic IC?

A: RoHS3 compliance indicates adherence to current environmental and material restriction standards. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, the Texas Instruments parts (SN74ACT00N and SN74ACT00NE4) are the appropriate selection.

Q: Does the higher quiescent current of the CD74ACT00E (4 µA) impact circuit design?

A: The 2 µA difference in quiescent current is negligible for most applications. However, in power-sensitive designs or systems with large numbers of ICs, cumulative current draw may become relevant. The onsemi and Texas Instruments parts maintain lower quiescent current at 2 µA.

Q: What is the difference between the 14-MDIP and 14-PDIP package designations?

A: Both designations refer to 14-pin Dual Inline Packages with 0.300" (7.62mm) spacing. The packages are mechanically and electrically compatible for Through Hole mounting applications.
