SN74AC86DR

Overview

The SN74AC86DR is a quad 2-input exclusive-OR gate manufactured by Texas Instruments. It belongs to the AC logic series and utilizes CMOS technology. The device operates within a supply voltage range of 2 V to 6 V. It features buffered inputs and outputs, with a low-level output current of 24 mA and a high-level output current of -24 mA. The propagation delay is specified at 8.5 ns under standard test conditions (5 V, 50 pF load). The component supports surface-mount installation in a 14-SOIC package and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Contains four independent dual-input exclusive-OR gates performing Boolean XOR functions.
• Provides buffered input and output structures for signal integrity.
• Supports wide supply voltage operation from 2 V to 6 V.

Applications

• Digital data processing circuits requiring parity generation or checking.
• Arithmetic logic units implementing addition and subtraction operations.
• Comparators for detecting inequality between binary data words.

Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-14 package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the specified 24 mA output drive capability and 8.5 ns propagation delay characteristics for timing closure.

Selection Notes

Select this component when a wide 2 V to 6 V supply range is required compared to standard 5 V only logic families. The 24 mA output drive strength supports moderate capacitive loads without external buffering. Consider the 8.5 ns propagation delay for system clock speeds and ensure the SOIC-14 footprint matches the PCB layout constraints.

Part Context

This part is a member of the Texas Instruments 74AC logic family, which offers higher speed performance than legacy LS series devices while maintaining CMOS power efficiency. The SN74AC86 specifically implements the XOR function, distinct from AND, OR, or NAND variants within the same package lineup. It serves as a fundamental building block for complex digital arithmetic and control logic systems.

Replacement Considerations

SN74AC86N: PDIP-14 variant with identical electrical specifications but through-hole mounting. CD74AC86M: Alternative manufacturer version in SOIC-14 package. Verify pinout compatibility and parameter tolerances before substitution.
