SN74AHCT1G86DBVT

Overview

The SN74AHCT1G86DBVT is a single-channel exclusive-OR (XOR) gate from the Texas Instruments SN74AHCT1G series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a SOT-23-5 surface-mount package. The device provides symmetric output drive capabilities with low-level and high-level output currents of 8 mA each. It exhibits a maximum propagation delay of 7.9 ns at 5 V with a 50 pF load. The component supports an operating temperature range from -40 °C to +125 °C and includes static protection exceeding 3000 V per the JEDEC JESD22 standard.

Feature Summary

• Implements single-channel XOR logic function for signal comparison or parity generation
• Ensures compatibility with standard 5-V CMOS devices through HCT input thresholds
• Provides robust electrostatic discharge protection for reliable operation in sensitive environments

Applications

• Digital data path selection and multiplexing circuits
• Parity error detection and generation modules
• Comparator logic for binary value verification

Procurement Notes

Verify the specific suffix DBVT corresponds to the SOT-23-5 package and tape-and-reel shipping configuration. Confirm that the AHCT designation aligns with the required 5-V system interface, as it differs from the AHC series which accepts lower voltages. Ensure the automotive or industrial temperature rating matches the operational environment requirements before finalizing procurement.

Selection Notes

Select this component when a compact XOR solution is needed for 5-V digital systems requiring HCT-compatible inputs. The SOT-23-5 package offers space efficiency for dense PCB layouts. Consider the 8 mA drive strength for moderate capacitive loads. Verify that the 4.5 V minimum supply voltage meets the system power rail specifications, as lower voltage operation is not supported by the HCT variant.

Part Context

This part belongs to the SN74AHCT1Gxx family of single-function gates designed for high-speed CMOS applications. The AHCT series bridges the gap between advanced high-speed CMOS performance and traditional HC/HCT logic compatibility. These components are widely used in consumer electronics, computing peripherals, and industrial control systems where small form factors and reliable logic switching are essential.

Replacement Considerations

SN74AHCT1G86DBVR: Identical electrical characteristics and logic function; differs only in packaging format (tape-and-reel vs. cut tape). SN74AHC1G86DBVT: Similar performance but utilizes AHC input thresholds compatible with lower supply voltages; verify voltage compatibility.
