74AHCT86BQ,115

Overview

The Nexperia 74AHCT86BQ,115 is a quad 2-input EXCLUSIVE-OR gate housed in a DHVQFN14 (SOT762-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerance up to 5.5 V. It supports an ambient temperature range from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM).

Feature Summary

• Provides four independent 2-input EXCLUSIVE-OR logic functions.
• Accepts TTL-compatible input voltage levels for direct interfacing with Transistor-Transistor Logic systems.
• Incorporates Schmitt-trigger action on all inputs to ensure noise immunity against slow signal transitions.
• Features overvoltage tolerant inputs capable of handling signals up to the maximum supply voltage.

Applications

• Logic-level translation between mixed-voltage environments.
• Implementation of exclusive-OR logic operations in digital circuits.
• Signal processing requiring high noise immunity and defined switching thresholds.

Procurement Notes

Verify that the specific ordering suffix matches the required thermal enhanced very thin quad flat package configuration. Confirm the TTL input level specification aligns with the system interface requirements. Ensure the operating temperature range meets the environmental constraints of the final application design.

Selection Notes

Select this component when TTL input compatibility is required alongside CMOS output drive capabilities. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Consider the balanced propagation delay characteristics for timing-sensitive applications involving multiple XOR gates.

Part Context

This part belongs to the Nexperia 74AHC(AHCT)86 family of quad 2-input EXCLUSIVE-OR gates. The 'AHCT' designation specifically indicates TTL-compatible input thresholds, distinguishing it from standard AHC variants which utilize CMOS input levels. The BQ suffix identifies the DHVQFN14 surface-mount package variant.
