SN74AHCT86D

Overview

The SN74AHCT86D is a quadruple 2-input exclusive-OR gate in a 14-pin SOIC package. It operates on a 4.5 V to 5.5 V supply with TTL-compatible inputs (VIL=0.8 V, VIH=2 V). Propagation delay is 8.8 ns at 50 pF load. Output drive is ±8 mA. Operating temperature ranges from -40°C to 85°C.

Feature Summary

• TTL-voltage compatible inputs for 3.3 V to 5 V translation
• Low-drive CMOS design minimizes output ringing and overshoot
• ESD protection exceeds 2000-V Human-Body Model

Applications

• Server systems
• Network switches
• Telecom infrastructures

Procurement Notes

Verify the specific 'D' suffix indicates the SOIC-14 package variant. Confirm the operating temperature range matches the -40°C to 85°C specification for this part number. Ensure the device status is checked against the latest TI orderable addendum as some variants may be obsolete.

Selection Notes

Select this component when TTL input compatibility is required for 5 V logic interfaces. The low-drive characteristic is suitable for applications where output ringing must be minimized. Verify that the 8 mA output current meets the load requirements of the destination circuitry.

Part Context

This device belongs to the SNx4AHCT86 family of quadruple 2-input exclusive-OR gates. It utilizes CMOS technology to provide balanced output drive while maintaining compatibility with TTL logic levels. The family includes various package options such as SSOP, TSSOP, and VQFN.

FAQ

How does the SN74AHCT86D handle voltage translation?

The lowered switching thresholds allow it to translate signals up from 3.3 V to 5 V by accepting TTL-level inputs.

What is the function of the Boolean operation performed?

It performs the XOR function where the output is high if an odd number of inputs are active.
