74AHCT1G86DBVTG4

Overview

The SN74AHCT1G86DBVTG4 is a single-channel dual-input exclusive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and utilizes the HCT logic series, ensuring compatibility with standard TTL levels. The device is housed in a compact SOT-23-5 surface-mount package. Key electrical characteristics include a maximum propagation delay of 7.9ns at 5V with a 50pF load, output drive currents of ±8mA, and a maximum static current of 1µA. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Executes Boolean XOR function Y = A ⊕ B using positive logic
• Provides high-speed signal processing with low propagation delay
• Features robust output drive capability for reliable interfacing
• Designed for operation across extended industrial temperature ranges

Applications

• Digital logic circuits requiring parity generation or checking
• Arithmetic logic units performing binary addition operations
• Data path switching and multiplexing control logic
• General-purpose digital signal processing applications

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and specific manufacturing traceability. Ensure the ordering code matches the required SOT-23-5 package variant. Confirm that the HCT logic family specifications align with the system's voltage and timing requirements before finalizing procurement orders.

Selection Notes

Select this component when a single XOR gate is required in a minimal footprint application. The HCT series ensures direct compatibility with 5V TTL logic inputs. Consider the SOT-23-5 package constraints regarding thermal dissipation and PCB space. Verify that the 5V supply voltage range meets the target circuit design parameters.

Part Context

This component belongs to the SN74AHCT1G86 family of single-gate logic ICs. It shares functional similarities with other single-gate XOR devices but is distinguished by its HCT input structure and specific packaging. The DBVTG4 designation indicates the specific tape-and-reel packaging and lead-free construction used for automated assembly processes.

Replacement Considerations

Direct substitutes include SN74AHCT1G86DBVR and SN74AHCT1G86DCKR, which offer identical logical functionality and pinout configurations. These alternatives may differ only in packaging style or reel specifications while maintaining compatible electrical performance.
