SN74AC00PWE4 Equivalent & Substitute Parts

Part Overview

The SN74AC00PWE4 is a NAND Gate IC with 4 channels and 2 inputs per channel, manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The 74AC00 logic family provides standard NAND gate functionality across multiple manufacturers and packaging options, enabling direct functional replacement where electrical and mechanical parameters align.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AC00PWE4 is determined by strict alignment of electrical and mechanical parameters. All substitute parts must maintain identical logic function (4-channel NAND gate with 2 inputs), identical supply voltage range (2V ~ 6V), identical output current specifications (24mA high and low), identical input logic levels, identical propagation delay (8ns @ 5V, 50pF), and identical package type (14-TSSOP surface mount).

The substitute parts are grouped as follows:

Direct Substitutes (Identical Electrical Parameters):

• SN74AC00PWR (Texas Instruments, Tape & Reel packaging)
• SN74AC00PW (Texas Instruments, Tube packaging)
• 74AC00MTCX (onsemi, Tape & Reel packaging)
• 74AC00MTC (onsemi, Tube packaging)

Extended Temperature Range Substitute (Broader Operating Specification):

• MC74AC00DTR2G (onsemi, Cut Tape & Digi-Reel packaging) — Operating temperature -55°C ~ 125°C with quiescent current of 4 µA maximum

All substitutes share the base product number 74AC00, identical package dimensions, and RoHS3 compliance. Differences exist only in manufacturer, packaging format, product status, and in one case, extended temperature range and slightly elevated quiescent current.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Active Product Status: SN74AC00PWR is the primary substitute. It is manufactured by Texas Instruments, maintains identical electrical specifications to the SN74AC00PWE4, and carries Active product status with high inventory availability (30,400 pcs). The only difference is packaging format (Tape & Reel versus the original tube packaging). This part is suitable for new production and maintenance applications requiring immediate availability.

For Extended Temperature Range Applications: MC74AC00DTR2G is suitable when operating temperature range must extend to -55°C or +125°C. This onsemi part maintains all electrical parameters except quiescent current (4 µA maximum versus 2 µA), which remains within acceptable limits for most applications. Product status is Active with substantial inventory (20,300 pcs). The Cut Tape & Digi-Reel packaging format differs from the original.

For onsemi Manufacturer Preference: 74AC00MTCX provides an Active status alternative from onsemi with identical electrical specifications to the SN74AC00PWE4. Inventory is available (1,759 pcs) in Tape & Reel packaging.

Parts to Avoid for New Designs: 74AC00MTC (onsemi, Obsolete status) and SN74AC00PW (Texas Instruments, Discontinued at DiGi Electronics) should not be selected for new production due to product status, though limited inventory remains available.

Frequently Asked Questions (FAQ)

Q: Can SN74AC00PWR directly replace SN74AC00PWE4 on the PCB? A: Yes. Both parts are identical in electrical function, pin configuration, and 14-TSSOP package dimensions. The only difference is packaging format (Tape & Reel versus tube). No circuit modifications are required.

Q: What is the difference between the packaging options (Tube, Tape & Reel, Cut Tape)? A: Packaging format affects how components are supplied and handled during assembly. Tube packaging is for manual handling or lower-volume assembly. Tape & Reel and Cut Tape & Digi-Reel are for automated pick-and-place assembly. All three formats contain identical die and electrical performance. Selection depends on assembly process requirements, not circuit function.

Q: Why does MC74AC00DTR2G have a higher quiescent current (4 µA vs 2 µA)? A: MC74AC00DTR2G is specified for extended temperature range (-55°C ~ 125°C). The higher quiescent current specification reflects the broader operating envelope. For applications within the standard -40°C ~ 85°C range, this difference is not functionally significant.

Q: Can I use MC74AC00DTR2G in place of SN74AC00PWE4 if my circuit only operates at -40°C ~ 85°C? A: Yes. MC74AC00DTR2G is electrically compatible within the standard temperature range. The extended temperature specification and slightly higher quiescent current do not create incompatibility. This substitution is valid for standard temperature applications.

Q: Why are some substitute parts listed as Discontinued or Obsolete? A: Product status reflects manufacturer and distributor availability at the time of data collection. Discontinued and Obsolete parts may have limited remaining inventory. For new production, select parts with Active status: SN74AC00PWR, 74AC00MTCX, or MC74AC00DTR2G.

Q: Are all these parts RoHS3 compliant? A: Yes. All listed parts carry RoHS3 Compliant status and MSL Level 1 (Unlimited moisture sensitivity), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the base product number 74AC00? A: The 74AC00 is the base logic function designation. All listed parts implement the same 4-channel NAND gate logic. Variations in part numbers reflect manufacturer, packaging, and product status differences, not functional differences.
