74AHCT86T14-13 Equivalent & Substitute Parts

Part Overview

The 74AHCT86T14-13 is a 4-channel XOR (Exclusive OR) logic gate IC manufactured by Diodes Incorporated in a 14-TSSOP surface mount package. This device implements exclusive OR logic functions across four independent channels with 2 inputs per channel. The part is currently active in production with 1076 units in stock.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple manufacturers is needed for supply chain resilience. The substitute parts listed maintain functional and electrical equivalence while potentially offering different availability, packaging options, or manufacturer-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74AHCT86T14-13 is determined by the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Package / Case: 14-TSSOP form factor
• Supply Voltage Range: 4.5V ~ 5.5V minimum requirement
• Output Current Capability: 8mA minimum for both high and low states
• Input Logic Levels: 0.8V (low) and 2V (high) thresholds
• Propagation Delay: Maximum 10ns at 5V with 50pF load
• Operating Temperature: -40°C to 125°C range
• RoHS3 Compliance and MSL Level 1

Substitute parts must maintain all functional logic specifications, identical pin configuration in the 14-TSSOP package, and equivalent electrical performance within the specified parameters. Variations in quiescent current, propagation delay, or supply voltage range that remain within acceptable engineering tolerances are permissible.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the 74AHCT86T14-13 within the specified electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

74AHCT86PW,118 (Nexperia USA Inc.): Direct parametric equivalent with improved quiescent current performance (2 µA vs. 20 µA) and faster propagation delay (8.8ns vs. 10ns). Maintains identical supply voltage range and operating temperature. Tape & Reel packaging. High inventory availability (8149 units).

SN74AHCT86PWR (Texas Instruments): Direct parametric equivalent with improved quiescent current and propagation delay. Operating temperature range limited to -40°C ~ 85°C. Cut Tape & Digi-Reel packaging. Highest inventory availability (103162 units). Suitable for applications not requiring extended temperature operation above 85°C.

MC74VHCT86ADTR2G (onsemi): Extended supply voltage range (2V ~ 5.5V) provides compatibility with lower voltage systems. Improved quiescent current and propagation delay. Operating temperature range -55°C ~ 85°C. Tape & Reel packaging. Suitable for applications requiring lower supply voltage operation or extended low-temperature performance.

SN74AHCT86PW (Texas Instruments): Functionally equivalent with improved performance characteristics. Product status is discontinued at DiGi Electronics. Operating temperature limited to -40°C ~ 85°C. Tube packaging. Limited inventory (776 units). Not recommended for new designs due to discontinuation status.

All parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 14-TSSOP package geometry. Selection should prioritize parts with active product status and adequate inventory for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74AHCT86T14-13 be directly replaced with any of the listed substitutes?

A: Yes, all listed substitute parts are functionally equivalent and pin-compatible in the 14-TSSOP package. Direct PCB substitution is possible without circuit modification. However, verify that the operating temperature range and supply voltage specifications of the substitute meet your application requirements.

Q: What is the difference between the 74AHCT and 74VHCT series?

A: The 74AHCT series operates at 4.5V ~ 5.5V supply voltage. The 74VHCT series (MC74VHCT86ADTR2G) extends the supply voltage range to 2V ~ 5.5V, enabling operation in lower voltage systems. Both series maintain identical logic function and pin configuration in the 14-TSSOP package.

Q: Why does the 74AHCT86T14-13 have higher quiescent current (20 µA) compared to other substitutes (2 µA)?

A: Quiescent current variation is a normal manufacturing difference between semiconductor vendors. The 74AHCT86T14-13 specification of 20 µA maximum is within acceptable engineering tolerance for this logic family. Substitute parts with lower quiescent current (2 µA) offer improved power efficiency but are functionally equivalent.

Q: Are there packaging format differences among the substitutes?

A: Yes. The 74AHCT86T14-13 and 74AHCT86PW,118 are supplied in Tape & Reel (TR) format. SN74AHCT86PWR is supplied in Cut Tape (CT) & Digi-Reel format. SN74AHCT86PW is supplied in Tube format. MC74VHCT86ADTR2G is supplied in Tape & Reel format. All maintain identical 14-TSSOP package geometry and are compatible with standard pick-and-place assembly equipment.

Q: Which substitute offers the best availability?

A: SN74AHCT86PWR from Texas Instruments has the highest inventory availability at 103162 units. This part is suitable for high-volume production requirements and offers active product status with improved electrical performance characteristics.

Q: Can the MC74VHCT86ADTR2G be used in a 5V system designed for the 74AHCT86T14-13?

A: Yes. The MC74VHCT86ADTR2G operates across 2V ~ 5.5V supply voltage range, which includes the 4.5V ~ 5.5V range of the 74AHCT86T14-13. The part is fully compatible with 5V system designs and offers the additional benefit of lower voltage operation capability.

Q: What is the significance of the operating temperature range difference?

A: The 74AHCT86T14-13 operates from -40°C ~ 125°C. Substitutes SN74AHCT86PWR and SN74AHCT86PW are limited to -40°C ~ 85°C. The MC74VHCT86ADTR2G extends to -55°C. Select substitutes based on your application's minimum and maximum operating temperature requirements. Extended temperature range parts are necessary for industrial or automotive applications requiring operation above 85°C.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts, including the 74AHCT86T14-13 and all substitutes, are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. This ensures compatibility with lead-free assembly processes and environmental compliance requirements.
