SN74AHC1G86DCKR

Overview

The SN74AHC1G86DCKR is a single-channel, two-input exclusive-OR (XOR) gate manufactured by Texas Instruments. It belongs to the AHC logic family and operates within a supply voltage range of 2V to 5.5V. The device is housed in a SC-70 package with five pins. It executes the Boolean function Y = AB + AB using positive logic. Key electrical characteristics include a maximum propagation delay of 11ns at 3.3V and output drive currents of ±8mA.

Feature Summary

• Executes exclusive-OR logic functions for digital signal processing
• Compatible with standard CMOS and TTL logic families
• Operates across a wide supply voltage range from 2V to 5.5V

Applications

• Digital data path switching and routing
• Parity generation and error detection circuits
• Arithmetic logic units for addition operations

Procurement Notes

Verify the specific ordering suffix DCKR to confirm the SC-70 package type and tape-and-reel packaging configuration. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when a single XOR gate is required in a compact surface-mount design. The AHC series offers improved speed compared to legacy HC devices while maintaining low power consumption. Verify that the operating voltage aligns with the system's 2V to 5.5V specification and that the SC-70 package fits the available board space constraints.

Part Context

This part is a member of the Texas Instruments SN74AHC1Gxx series, which provides single-function gates in ultra-small packages. The AHC series represents an advanced high-speed CMOS technology designed for general-purpose digital applications requiring fast switching speeds and low static power dissipation in modern electronic systems.
