Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AHCT86PW,112 is determined by the following critical parameters:

• Logic function: 4-channel XOR gate with 2 inputs per channel
• Supply voltage range: 4.5V ~ 5.5V (or wider compatible range)
• Output drive capability: 8mA high and low
• Propagation delay: 8.8ns maximum at 5V, 50pF load
• Package compatibility: 14-pin surface mount variants (TSSOP, SSOP, TVSOP)
• Input logic thresholds: 0.8V low, 2V high
• Operating temperature range: -40°C to 125°C minimum

Substitute parts are grouped into two categories:

Category A - Direct Functional Equivalents (14-TSSOP package): Parts maintaining identical electrical specifications and the same 14-TSSOP package footprint.

Category B - Package Variants (Alternative surface mount packages): Parts with equivalent electrical performance but different surface mount packages (14-SSOP, 14-TVSOP), requiring PCB layout adjustment.

Category C - Extended Voltage Range (14-TSSOP package): Parts with wider supply voltage specifications (2V ~ 5.5V) that maintain backward compatibility with the 4.5V ~ 5.5V requirement.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74AHCT86PWR (Texas Instruments)

The SN74AHCT86PWR is the preferred substitute. It maintains identical electrical specifications to the 74AHCT86PW,112, operates within the same 4.5V ~ 5.5V supply range, and is actively manufactured. The part is available in high inventory (103,162 pcs) and carries the same RoHS3 compliance and MSL Level 1 rating. The 14-TSSOP package is footprint-compatible with the original part.

Secondary Recommendation: SN74AHCT86PW (Texas Instruments)

This part provides identical electrical performance and package compatibility but is discontinued at DiGi Electronics. Use only if existing inventory is available and long-term procurement is not required.

Alternative for Extended Temperature Range: MC74VHCT86ADTR2G (onsemi)

This part extends the supply voltage range to 2V ~ 5.5V while maintaining the same propagation delay (8.8ns) and quiescent current (2 µA). However, the operating temperature range is reduced to -55°C ~ 85°C. Select this part only if the extended lower voltage operation is required and the reduced upper temperature limit is acceptable.

Package Variant Options:

• SN74AHCT86DBR (14-SSOP): Identical electrical performance with a wider 14-SSOP package (0.209", 5.30mm width). Requires PCB layout modification.
• SN74AHCT86DGVR (14-TVSOP): Identical electrical performance with a 14-TVSOP package. Requires PCB layout modification.

Not Recommended: 74AHCT86T14-13 (Diodes Incorporated)

While functionally equivalent, this part exhibits higher quiescent current (20 µA vs. 2 µA) and slightly longer propagation delay (10ns vs. 8.8ns). Use only if other options are unavailable.

Frequently Asked Questions (FAQ)

Q: Can I use SN74AHCT86PWR as a direct replacement for 74AHCT86PW,112?

A: Yes. The SN74AHCT86PWR is a direct replacement. Both parts share identical electrical specifications, the same 14-TSSOP package footprint, and equivalent RoHS3 and MSL certifications. No PCB modifications are required.

Q: What is the difference between 74AHCT86 and 74VHCT86 series?

A: The 74VHCT86 series (MC74VHCT86ADTR2G) supports a wider supply voltage range (2V ~ 5.5V) compared to the 74AHCT86 series (4.5V ~ 5.5V). Both maintain the same propagation delay and quiescent current specifications. The 74VHCT86 is suitable for applications requiring lower voltage operation.

Q: Why does 74AHCT86T14-13 have higher quiescent current?

A: The 74AHCT86T14-13 from Diodes Incorporated specifies a maximum quiescent current of 20 µA, compared to 2 µA for the original part. This difference is within the allowable parameter range for the 74AHCT86 logic family but may impact power consumption in battery-powered applications.

Q: Can I use SN74AHCT86DBR or SN74AHCT86DGVR without PCB changes?

A: No. These parts use different surface mount packages (14-SSOP and 14-TVSOP respectively) with different pin spacing and footprints. PCB layout modification is required. Use these only if your design can accommodate the alternative package geometry.

Q: Is the operating temperature range important for my application?

A: Yes. The original 74AHCT86PW,112 operates from -40°C to 125°C. Most active substitutes (SN74AHCT86PWR, SN74AHCT86DBR, SN74AHCT86DGVR) operate to -40°C ~ 85°C, which is acceptable for most industrial applications. The MC74VHCT86ADTR2G operates to -55°C ~ 85°C. Verify your application's temperature requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance and MSL Level 1 (unlimited) moisture sensitivity ratings, matching the original part's environmental certifications.
