SN74HC86PWT Equivalent & Substitute Parts

Part Overview

The SN74HC86PWT is a 4-channel XOR (Exclusive OR) logic gate IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The SN74HC86PWT operates across a 2V to 6V supply voltage range with low quiescent current and is suitable for general-purpose digital logic applications requiring XOR functionality.

Substitute Part Grouping Explanation

Substitution of the SN74HC86PWT is determined by strict equivalence across the following critical parameters:

Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
Package: 14-TSSOP surface mount form factor
Voltage Supply Range: 2V ~ 6V minimum requirement
Output Current Capability: 5.2mA minimum for both high and low states
Input Logic Levels: 0.5V ~ 1.8V (low) and 1.5V ~ 4.2V (high)
Propagation Delay: Maximum 20ns at 6V with 50pF load
Operating Temperature: Minimum -40°C to 85°C range
RoHS3 Compliance and MSL Level 1

Substitute parts must maintain compatibility across all these parameters. Parts with extended temperature ranges, improved quiescent current specifications, or faster propagation delays are considered parametric equivalents and direct substitutes. Parts with different logic functions, package types, or supply voltage ranges are excluded.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Identical Specifications)

SN74HC86PWR from Texas Instruments is the direct active equivalent to the obsolete SN74HC86PWT. Both parts share identical electrical specifications and differ only in packaging format (Cut Tape & Digi-Reel versus tube). This part is recommended for designs requiring continuity with the original specification.

Secondary Substitutes (Active Status, Extended Temperature Range)

74HC86PW,118 and 74HC86PW-Q100,118 from Nexperia USA Inc. are active alternatives with extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The 74HC86PW-Q100,118 variant includes AEC-Q100 automotive qualification. Propagation delay is specified at 20ns, which remains within acceptable limits for most applications. These parts are suitable for designs requiring extended temperature operation or automotive-grade components.

Alternative Substitutes (Active Status, Performance Variations)

MC74HC86ADTR2G from onsemi offers improved quiescent current (1 µA) and extended temperature range (-55°C to 125°C). 74HC86T14-13 from Diodes Incorporated provides faster propagation delay (15ns) but with higher quiescent current (20 µA). MM74HC86MTCX from Fairchild Semiconductor maintains the original temperature range with standard specifications.

Obsolete Alternatives (Not Recommended for New Designs)

NLV74HC86ADTR2G is classified as obsolete and should not be selected for new designs despite its extended temperature range and low quiescent current.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HC86PWR as a direct replacement for SN74HC86PWT?

A: Yes. SN74HC86PWR is the active equivalent from Texas Instruments with identical electrical specifications. The only difference is packaging format (Cut Tape & Digi-Reel versus tube). Electrical performance and pin configuration are identical.

Q: What is the difference between 74HC86PW,118 and 74HC86PW-Q100,118?

A: Both parts are from Nexperia with identical electrical specifications. The 74HC86PW-Q100,118 includes AEC-Q100 automotive qualification and is suitable for automotive applications. Select based on application requirements.

Q: Why does 74HC86T14-13 have different quiescent current (20 µA) than the original part (2 µA)?

A: 74HC86T14-13 from Diodes Incorporated has a higher quiescent current specification. This part remains functionally equivalent for XOR logic operations but may have different power consumption characteristics. Verify suitability for power-sensitive applications.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts maintain RoHS3 compliance and MSL Level 1 rating, consistent with the original SN74HC86PWT specifications.

Q: Can I use parts with extended temperature ranges in place of the original?

A: Yes. Parts with extended operating temperature ranges (-40°C to 125°C) are backward compatible with designs specified for -40°C to 85°C operation. Extended range provides additional design margin for temperature-sensitive applications.

Q: Is the 14-TSSOP package identical across all substitute parts?

A: Yes. All substitute parts use the 14-TSSOP (0.173", 4.40mm Width) surface mount package. Pin configuration and footprint are identical, allowing direct PCB substitution.

Q: Should I select MC74HC86ADTR2G for low-power applications?

A: MC74HC86ADTR2G offers the lowest quiescent current (1 µA) among active substitutes and extended temperature range (-55°C to 125°C). This part is suitable for battery-powered or low-power applications where quiescent current is a design constraint.
