74AHCT1G86SE-7

Overview

The Diodes Incorporated 74AHCT1G86SE-7 is a single 2-input positive exclusive-OR gate housed in an SOT353 package. It operates within a supply voltage range of 4.5V to 5.5V and provides ±8 mA output drive at 5.0V. The device features Schmitt trigger action at all inputs, ensuring tolerance for slower input rise and fall times. Electrical characteristics include high-level output voltage of 3.94V min at -8mA load and low-level output voltage of 0.36V max at 8mA load at 4.5V. Propagation delay is typically 3.5ns at 5V with 15pF load.

Procurement Notes

Verify the specific ordering suffix SE corresponds to the SOT353 package type when sourcing this component. Confirm that the -7 suffix indicates tape and reel packaging with a quantity of 3000 units per reel. Ensure compliance with RoHS directives and check for lead-free finish requirements. Validate that the supplier provides documentation confirming the green molding compound without bromine or antimony. Cross-reference the document number DS35185 Rev. 1-2 for accurate technical specifications during procurement.

Selection Notes

Select this component for applications requiring a single XOR gate in a compact SOT353 footprint. It is suitable for systems operating strictly between 4.5V and 5.5V. The Schmitt trigger inputs make it appropriate for signals with slow rise or fall times. Consider the ±8 mA drive capability for driving moderate loads. Ensure the design accommodates the specified thermal resistance values for the SOT353 package under expected ambient conditions.

Part Context

This part belongs to the 74AHCT1G series of logic gates, designed for operation with TTL-compatible input levels while utilizing CMOS technology. The AHCT family ensures compatibility with 5V systems. The 1G designation indicates a single gate per package. The 86 function code specifically denotes the exclusive-OR logic operation. This series is intended for general-purpose digital logic applications requiring low power and high noise immunity.

Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 74AHCT1G86 function in an SOT353 package. Verify pinout compatibility, specifically the arrangement of inputs A, B, ground, output Y, and VCC. Ensure alternative components meet the same electrical specifications for voltage range, drive current, and propagation delay. Confirm that any substitute also offers comparable ESD protection levels and operates within the same temperature range.
