SN74ACT86NSR

Overview

The SN74ACT86NSR is a quad 2-input exclusive-OR gate from the Texas Instruments SN74ACT series. It operates within a supply voltage range of 4.5V to 5.5V and features low quiescent current of 4 µA. The device provides high noise immunity and supports TTL-compatible inputs. Key electrical parameters include a propagation delay of 9.5 ns at 5V with 50pF load, and output drive currents of ±24 mA. It functions in temperatures from -40°C to +85°C and is housed in a 14-pin SOIC package.

Feature Summary

• Executes the Boolean function Y = A ⊕ B for four independent channels
• Features TTL-compatible input thresholds for direct interface with TTL logic
• Provides high noise immunity suitable for noisy industrial environments
• Offers low static power consumption due to CMOS construction

Applications

• Parity checkers and error detection circuits
• Binary adders and subtractors
• Logic level translation between different voltage domains
• Data routing and switching applications

Procurement Notes

Verify the specific suffix NSR indicates the tape-and-reel packaging format compatible with automated surface-mount assembly processes. Confirm that the component meets RoHS3 compliance standards required by your manufacturing facility. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape premiums or minimum order constraints during procurement.

Selection Notes

Select this component when designing systems requiring 5V operation with high-speed XOR functionality. The ACT series offers faster switching speeds compared to standard AC devices while maintaining lower power consumption than older LS families. Consider the SOIC-14 package dimensions for PCB layout constraints and thermal management requirements in dense circuit designs.

Part Context

This part belongs to the SN74ACT family of advanced CMOS logic gates, bridging the performance gap between standard AC and ALST families. The SN74ACT86 specifically implements the exclusive-OR logic function, widely used in digital signal processing and arithmetic logic units. It serves as a core building block for complex combinational logic circuits in automotive and industrial control systems.
