Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HCT86DB,112 is determined by the following critical parameters:

• Logic Function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Supply Voltage Range: 4.5V ~ 5.5V compatibility
• Package Type: 14-SSOP surface mount form factor
• Input/Output Logic Levels: 0.8V low threshold, 2V high threshold
• Mounting Configuration: Surface mount technology

The SN74AHCT86DBR from Texas Instruments meets all substitution criteria. Both parts operate within the same voltage supply range, share identical logic function architecture, use the same 14-SSOP package footprint, and maintain compatible input/output logic level specifications. The substitute part is classified as active product status, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The SN74AHCT86DBR qualifies as a direct substitute for the 74HCT86DB,112 based on functional equivalence and regulatory compliance. Both parts maintain ROHS3 compliance and operate within the same supply voltage specification. The substitute part carries active product status from Texas Instruments, ensuring long-term availability and manufacturing continuity.

The SN74AHCT86DBR demonstrates performance advantages over the original part: output current capability is doubled (8mA versus 4mA), and propagation delay is significantly reduced (8.8ns versus 32ns). These characteristics make the substitute suitable for applications requiring improved speed and drive capability. The operating temperature range of the substitute (-40°C to 85°C) is narrower than the original (-40°C to 125°C); applications requiring operation above 85°C must retain the original part or identify alternative solutions.

Both parts use identical 14-SSOP packaging and surface mount configuration, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74AHCT86DBR replace the 74HCT86DB,112 in existing designs?

A: Yes. Both parts share identical logic function (4-channel XOR), supply voltage range (4.5V ~ 5.5V), input/output logic levels, and 14-SSOP package footprint. No circuit modifications or PCB redesign is required.

Q: What are the key differences between these parts?

A: The substitute part (SN74AHCT86DBR) offers faster propagation delay (8.8ns versus 32ns) and higher output current (8mA versus 4mA). The original part supports a wider operating temperature range (-40°C to 125°C versus -40°C to 85°C).

Q: Are there any compatibility concerns with the 14-SSOP package?

A: No. Both parts use identical 14-SSOP (0.209", 5.30mm width) surface mount packaging. Pin configuration and footprint are equivalent, allowing direct substitution on existing PCBs.

Q: What is the product status difference, and why does it matter?

A: The 74HCT86DB,112 is classified as obsolete, indicating discontinued manufacturing. The SN74AHCT86DBR is active product, ensuring ongoing availability, manufacturing support, and technical documentation from Texas Instruments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and carry identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Q: Which part should I select for new designs?

A: The SN74AHCT86DBR is recommended for new designs due to active product status, superior performance characteristics, and guaranteed long-term availability from Texas Instruments.
