Overview
The SN74AHC86BQAR is a commercial-grade quadruple 2-input exclusive-OR gate in the AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature from -40°C to +125°C. The device provides high-speed performance with propagation delays as low as 6.3 ns at 5 V with 50 pF load. It features push-pull outputs capable of sourcing and sinking up to 8 mA, ensuring robust signal integrity across various digital logic applications.
Feature Summary
- Performs Boolean XOR function Y = A ⊕ B for four independent channels
- Provides enhanced electrostatic discharge protection exceeding JESD standards
- Offers latch-up performance exceeding 250 mA per JESD 17
- Supports wide supply voltage operation from 2 V to 5.5 V
Applications
- Detect phase differences in input signals
- Create selectable inverters or buffers
- Implement parity checking functions
Procurement Notes
Verify the specific BQA package designation (WQFN) matches the target PCB footprint. Confirm that the commercial rating (-40°C to +125°C) aligns with environmental requirements. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference the latest orderable addendum for current production status and lead-free finish specifications.
Selection Notes
Select this component when four independent XOR gates are required in a compact surface-mount form factor. The WQFN package offers thermal advantages over larger packages. Consider the 2-V to 5.5-V operating range for compatibility with varying logic levels. Verify that the 8-mA output drive capability meets the capacitive load requirements of the destination inputs.
Part Context
This part belongs to the Texas Instruments SNx4AHC86 family of quadruple 2-input exclusive-OR gates. The 'SN' prefix indicates commercial grade, while 'AHC' denotes advanced high-speed CMOS technology. The 'BQAR' suffix specifies the WQFN 14-pin package, tape-and-reel packaging, and RoHS compliance. It serves as a standard logic solution for boolean operations in digital circuits.
Replacement Considerations
Direct pin-compatible alternatives include SN74AHC86DRG4 (SOIC), SN74AHC86PWR (TSSOP), and SN74AHC86DBR (SSOP). These variants share identical electrical characteristics but differ in physical package dimensions and mounting style.
