Overview
The SN74AHCT86NSR 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 low-level output current of 8 mA and high-level output current of -8 mA. The device provides propagation delays of 1 ns to 9 ns depending on load capacitance and temperature, and includes ESD protection exceeding 2000 V via the human-body model.
Feature Summary
- TTL-voltage compatible inputs allow for direct interfacing with legacy logic families
- Low-drive CMOS architecture minimizes output ringing and overshoot on bus interfaces
- High latch-up performance ensures robust operation under electrical stress conditions
Applications
- Server systems
- PCs and notebooks
- Network switches
- Wearable health and fitness devices
- Telecom infrastructures
Procurement Notes
Verify the specific NS package designation (SOP, 14-pin) against the datasheet package information table to ensure correct physical dimensions. Confirm that the ordering suffix matches the required tape and reel specifications for automated assembly processes.
Selection Notes
Select this component when TTL input compatibility is required alongside CMOS drive capabilities. Ensure the application environment stays within the recommended operating temperature range of -40°C to 125°C. Verify that the 8 mA output drive current meets the load requirements without exceeding absolute maximum ratings.
Part Context
This part belongs to the SNx4AHCT86 family of quadruple 2-input exclusive-OR gates. It utilizes advanced CMOS technology to provide balanced output drive while maintaining compatibility with TTL logic levels. The device is designed for applications requiring up-translation from 3.3 V to 5 V systems.

FAQ
How does the SN74AHCT86NSR handle voltage translation?
The lowered switching thresholds accommodate TTL inputs, making the device ideal for translating signals up from 3.3 V to 5 V.
What is the function of unused inputs?
All unused inputs must be connected to either VCC or GND to prevent undefined operational states caused by floating voltages.
