74AHCT86PW,118

Overview

The Nexperia 74AHCT86PW,118 is a quad 2-input exclusive-OR gate housed in a TSSOP14 (SOT402-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-compatible input levels and overvoltage tolerant inputs up to 5.5 V. Static characteristics include a maximum low-level output voltage of 0.55 V at 8.0 mA load current. Dynamic performance specifies a typical propagation delay of 3.4 ns at 15 pF load capacitance.

Feature Summary

• Provides four independent 2-input exclusive-OR logic functions
• Features TTL-compatible input voltage thresholds for direct interfacing with TTL systems
• Includes Schmitt-trigger action on all inputs to improve noise immunity
• Offers overvoltage tolerant inputs allowing operation in mixed-voltage environments

Applications

• Translating signals between mixed voltage logic domains
• Implementing parity checkers and error detection circuits
• Constructing binary adder circuits

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Ensure the datasheet revision aligns with your design specifications before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed XOR functionality. The wide operating temperature range makes it suitable for industrial applications. Verify that the 4.5 V minimum supply voltage requirement fits within your system power budget constraints.

Part Context

This part belongs to the 74AHC/AHCT family of high-speed CMOS logic devices manufactured by Nexperia. The AHCT variant specifically bridges the gap between standard CMOS technology and legacy TTL logic families. It shares functional similarities with other 74-series logic gates but offers improved switching speeds and lower power consumption compared to older technologies.

Replacement Considerations

Check for alternative packages such as SO14 or DHVQFN14 if footprint changes are permissible. Verify pinout compatibility with existing PCB layouts before substituting with similar quad XOR gates from other manufacturers.
