SN74AHC86DBR

Overview

The SN74AHC86DBR is a quad 2-input exclusive-OR gate manufactured by Texas Instruments. It belongs to the AHC logic series and utilizes CMOS technology. The device operates within a supply voltage range of 2 V to 5.5 V. It features low input capacitance and supports high-speed operation with propagation delays typically around 10 ns at 5 V. The component provides symmetrical output drive currents of 8 mA for both high and low states. It is housed in a 14-pin SOIC package and is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent 2-input exclusive-OR logic functions within a single integrated circuit.
• Operates across a wide supply voltage range from 2 V to 5.5 V, ensuring compatibility with various digital systems.
• Features low static power consumption and high noise immunity characteristic of advanced CMOS technology.
• Supports surface-mount installation in compact 14-pin packages suitable for automated assembly.

Applications

• Data acquisition and processing circuits requiring parity generation or checking.
• Arithmetic logic units performing addition and subtraction operations.
• Digital comparison circuits identifying differences between binary signals.
• Control logic for error detection in communication interfaces.

Procurement Notes

Verify the specific suffix 'DR' corresponds to the standard 14-SOIC package and tape-and-reel packaging configuration. Confirm RoHS compliance status and manufacturing origin details against the latest datasheet revision. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multiple XOR gates in a compact form factor. The AHC series offers superior speed compared to legacy HC devices while maintaining low power consumption. Consider the 2 V to 5.5 V operating range for flexibility in mixed-voltage environments. Evaluate the 14-SOIC package dimensions against available PCB space constraints. Verify that the required propagation delay meets the timing specifications of the target application.

Part Context

This part is a member of the Texas Instruments SN74AHC86 family, which includes variants with different packaging options such as TSSOP and DGV. The 'DR' suffix specifically denotes the SOIC-14 package type with tape-and-reel shipping. It shares functional equivalence with other AHC86 derivatives but differs in physical footprint and handling characteristics. The family is designed for general-purpose digital logic applications requiring reliable XOR functionality.

Replacement Considerations

Direct replacements include SN74AHC86D and SN74AHC86N, provided the package type matches the design requirements. Alternative packages like SN74AHC86PWR offer identical electrical performance in a TSSOP format. Verify pinout compatibility and thermal characteristics when substituting with different package variants from the same logical family.
