Overview
The SN74AHCT86DBR is a quadruple 2-input exclusive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs with defined thresholds of 0.8 V for low-level and 2 V for high-level logic states. The device provides balanced output drive currents of up to 8 mA in both directions. Propagation delay typically ranges from 1 ns to 9 ns depending on load capacitance and temperature conditions. It is housed in a 14-pin SSOP package.
Feature Summary
- TTL-voltage compatible inputs allow direct interfacing with legacy logic families
- Low-drive CMOS architecture minimizes output ringing and overshoot
- High electrostatic discharge protection exceeds standard industry requirements
Applications
- Server systems
- PCs and notebooks
- Network switches
- Wearable health and fitness devices
- Telecom infrastructures
Procurement Notes
Verify the specific ordering suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel carrier configuration. Confirm that the RoHS compliance status and lead finish match project requirements. Ensure the moisture sensitivity level rating aligns with the assembly process timeline. Validate that the operating temperature range meets environmental specifications.
Selection Notes
Select this component when TTL compatibility is required for 3.3 V to 5 V translation applications. The slow edge rates make it suitable for bus interfaces where signal integrity is critical. Consider the thermal resistance values if multiple gates are utilized simultaneously. Verify input handling capabilities against system voltage levels.
Part Context
This part belongs to the SNx4AHCT86 family of quadruple 2-input exclusive-OR gates. The family includes variants with different packaging options such as SOIC, TSSOP, and VQFN. All members share identical electrical characteristics and logical functions while differing in physical dimensions and thermal properties.

FAQ
How does the device handle unused inputs?
All unused inputs must be connected to either VCC or GND to prevent undefined operational states.
What is the function of the Boolean operation performed?
The device performs the exclusive-OR function where the output is active high only when inputs differ.
