SN74AHC86PW

Overview

The SN74AHC86PW is a quad 2-input exclusive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features low static power consumption with a maximum quiescent current of 2 µA. The device utilizes AHC logic technology, providing high-speed performance with a typical propagation delay of 8.8 ns at 5 V with a 50 pF load. It supports output drive currents of 8 mA for both high and low states. The component is housed in a 14-TSSOP surface-mount package and is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates four independent 2-input exclusive-OR logic functions within a single package.
• Supports wide supply voltage operation ranging from 2 V to 5.5 V for flexible system integration.
• Delivers high-speed switching capabilities suitable for demanding digital applications.
• Ensures robust noise immunity and stable logic levels across the specified operating temperature range.

Applications

• Digital signal processing circuits requiring logical XOR operations
• Parity checkers and error detection modules
• Binary adder circuits in arithmetic logic units
• Data path selection and multiplexing logic

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel specifications, as variations exist within the AHC family. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure that the selected variant matches the required lead frame finish and moisture sensitivity level for your assembly process. Cross-reference the manufacturer part number against authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a quad XOR configuration is required with low power consumption and high speed. The 2 V to 5.5 V supply range makes it suitable for both 3.3 V and 5 V systems. Consider the TSSOP-14 package for space-constrained surface-mount designs. Compare propagation delays and output drive requirements against other logic families like HC or AC if higher current or different voltage thresholds are needed.

Part Context

This part belongs to the SN74AHC86 series of single-function gates produced by Texas Instruments. It is part of the broader 74AHC logic family, which combines the high speed of advanced CMOS technology with low power dissipation. The series includes various packages and variants designed for general-purpose digital logic applications in consumer, industrial, and computing equipment.

Replacement Considerations

Direct pin-compatible alternatives include SN74AHC86DR and SN74AHC86PWR from Texas Instruments. Other manufacturers may offer equivalent parts under different part numbers, but electrical characteristics and package dimensions must be verified. Ensure that any substitute maintains the same logic function, voltage range, and temperature rating.
