SN74LVC00ADBRE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC00ADBRE4 is a NAND Gate IC with 4 channels and 2 inputs per channel, manufactured by Texas Instruments in a 14-SSOP package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The device operates across a supply voltage range of 1.65V to 3.6V with low quiescent current and is suitable for low-voltage logic applications requiring NAND gate functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LVC00ADBRE4 is determined by the following critical parameters:

• Logic Function: All substitutes must provide 4-channel NAND gate functionality with 2 inputs per channel
• Supply Voltage Compatibility: Substitute parts must operate within or encompass the 1.65V ~ 3.6V range
• Output Drive Capability: Current output specifications (24mA high and low) must be maintained
• Propagation Delay: Maximum delay at 3.3V with 50pF load must not significantly exceed 4.1ns for timing-critical applications
• Operating Temperature Range: Must support -40°C ~ 125°C minimum
• Package Compatibility: Surface mount packages with equivalent pinouts (14-SSOP or 14-TSSOP variants)
• Compliance: ROHS3 compliance and EAR99 classification required

Three active substitute parts meet these criteria with varying trade-offs in voltage range, quiescent current, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC00ADBR (Texas Instruments) is the primary recommended substitute. It maintains identical electrical specifications and operating temperature range (-40°C ~ 125°C) as the obsolete SN74LVC00ADBRE4, with the only difference being packaging format (Tape & Reel versus bulk). This part is currently in active production status with 3200 units in stock, ensuring long-term availability. The identical supply voltage range (1.65V ~ 3.6V) and propagation delay (4.1ns @ 3.3V, 50pF) provide direct functional equivalence.

74LVC00APW,118 (Nexperia USA Inc.) offers an extended lower supply voltage limit (1.2V ~ 3.6V) and maintains the full operating temperature range (-40°C ~ 125°C). Propagation delay is marginally higher at 4.3ns. Quiescent current is elevated at 40 µA compared to 1 µA in the main part. This substitute is suitable for applications requiring lower voltage operation but with increased standby power consumption. Package is 14-TSSOP (0.173", 4.40mm width), requiring PCB layout adjustment.

74LCX00MTCX (onsemi) provides the highest inventory availability (81219 units) and maintains identical output drive capability. However, this part has a reduced operating temperature range (-40°C ~ 85°C), making it unsuitable for applications requiring the full 125°C upper limit. Quiescent current is 10 µA, and propagation delay is 5.2ns. The supply voltage range is narrower (2V ~ 3.6V), excluding operation below 2V. Package is 14-TSSOP format.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC00ADBR be used as a direct replacement for SN74LVC00ADBRE4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 125°C), and propagation delay (4.1ns @ 3.3V, 50pF). The difference is packaging format: the main part uses bulk packaging while the substitute uses Tape & Reel. Pinout and functionality are identical.

Q: What are the package differences between 14-SSOP and 14-TSSOP?

A: Both are 14-pin surface mount packages with identical pinouts. The 14-SSOP (Shrink Small Outline Package) has a body width of 0.209" (5.30mm), while the 14-TSSOP (Thin Shrink Small Outline Package) has a narrower body width of 0.173" (4.40mm). PCB footprints differ; designs using 14-SSOP cannot directly accommodate 14-TSSOP without layout modification.

Q: Which substitute should I select if my application operates below 2V?

A: The 74LCX00MTCX has a minimum supply voltage of 2V and is not suitable. Choose either SN74LVC00ADBR (1.65V minimum) or 74LVC00APW,118 (1.2V minimum). The Nexperia part offers the lowest voltage operation at 1.2V.

Q: Does the higher quiescent current in 74LVC00APW,118 affect my design?

A: The 74LVC00APW,118 has a quiescent current of 40 µA compared to 1 µA in the main part. For battery-powered or ultra-low-power applications, this 40x increase in standby current may be significant. For standard applications, the impact is typically negligible.

Q: Can I use 74LCX00MTCX in an application requiring 125°C operation?

A: No. The 74LCX00MTCX operating temperature range is -40°C ~ 85°C, which does not meet the 125°C upper limit requirement. Use SN74LVC00ADBR or 74LVC00APW,118 for full temperature range support.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three substitute parts and the main part are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements.
