74AHCT86D,118

Overview

The Nexperia 74AHCT86D,118 is a quad 2-input EXCLUSIVE-OR gate housed in an SO14 plastic small outline package (SOT108-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-compatible input levels, balanced propagation delays, and Schmitt-trigger actions on all inputs. Static characteristics include low leakage current and high noise immunity.

Feature Summary

• TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems
• Overvoltage tolerant inputs allowing operation in mixed voltage environments up to 5.5 V
• Schmitt-trigger action on all inputs to ensure high noise immunity

Applications

• Mixed voltage logic translation between CMOS and TTL domains
• Digital signal processing requiring exclusive-OR functionality
• Parity generation and checking circuits

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified temperature and voltage limits. Ensure design compliance with ESD protection standards and latch-up performance requirements defined in the product data sheet before finalizing procurement.

Selection Notes

Select this component when TTL-level inputs are required alongside high-speed XOR operations. The AHCT series provides compatibility with standard 5 V logic families while maintaining the speed advantages of advanced CMOS technology. Verify that the SO14 package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the 74AHC/AHCT logic family, which combines high-speed CMOS performance with TTL-compatible inputs. The 'D' suffix indicates the SO14 package type, while '118' denotes the standard tape and reel packaging configuration used for automated surface-mount assembly processes.

Replacement Considerations

Cross-reference with other manufacturers offering 74AHCT86 equivalents in SOIC-14 packages. Verify pinout compatibility and electrical parameter alignment, particularly propagation delay and output drive strength, before substituting.
