SN74AHCT1G86DBVR

Overview

The SN74AHCT1G86DBVR is a single-channel exclusive-OR gate from the Texas Instruments SN74AHCT1G86 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features two inputs with one output. The device provides an output current capability of 8 mA for both high and low states. Propagation delay is specified at 7.9 ns when driven at 5 V with a 50 pF load. It is housed in a surface-mount SOT-23-5 package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Implements exclusive-OR logic function within a single integrated circuit channel
• Compatible with standard 5-V CMOS logic families through HCT input structures
• Designed for surface-mount assembly using compact SOT-23-5 packaging

Applications

• Digital signal processing circuits requiring binary comparison
• Data path selection and switching logic
• Parity generation and error detection systems

Procurement Notes

Verify the complete part number including the suffix DBVR to confirm the specific tape-and-reel or cut-tape packaging configuration intended for your manufacturing process. Confirm that the AHCT logic family compatibility aligns with your system's 5-V interface requirements. Ensure thermal management strategies account for the maximum operating junction temperature limits defined in the official datasheet specifications.

Selection Notes

Select this component when a single XOR gate is required in a space-constrained design utilizing 5-V logic levels. The AHCT series ensures compatibility with older 5-V TTL standards while maintaining CMOS power efficiency. Consider the SOT-23-5 footprint constraints during PCB layout planning to ensure adequate clearance for the small outline transistor package dimensions.

Part Context

This device belongs to the SN74AHCT1Gxx family of single-function gates manufactured by Texas Instruments. These components are designed to provide basic logic functions in minimal footprints suitable for portable and space-limited electronic applications. The AHCT designation indicates compatibility with 5-V CMOS devices, bridging legacy TTL interfaces with modern low-power CMOS technologies.

Replacement Considerations

SN74AHC1G86DBVR offers similar functionality but operates over a wider voltage range of 2.0 V to 5.5 V. SN74AHCT1G86DCKR provides identical electrical characteristics in a smaller X2SON-5 package. Verify pinout compatibility and voltage level thresholds before substituting these alternative packages.
