SN74HC86NSR

Inverter Gates Overview

The SN74HC86NSR is a Texas Instruments quadruple 2-input XOR gate in the HC logic family. It operates on a supply voltage of 2 V to 6 V and supports fanout up to 10 LSTTL loads. The device features buffered inputs, balanced CMOS push-pull outputs, and clamp diodes for protection. It provides four independent gates performing the Boolean function Y = A ⊕ B. The NS package is a 14-pin Small Outline Package (SOP) with dimensions of 10.20 mm by 5.30 mm. It is RoHS compliant and lead-free.

Inverter Gates Feature Summary

• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents.
• Buffered inputs support fanout up to 10 LSTTL loads.
• Standard CMOS inputs feature high impedance and internal clamping diodes.

Inverter Gates Applications

• Detect phase differences in input signals
• Create a selectable inverter or buffer

Inverter Gates Procurement Notes

Verify the SN74HC86NSR datasheet revision F (April 2021) for accurate electrical characteristics and thermal metrics. Confirm the SOP-14 package outline matches design requirements. Ensure unused inputs are terminated to VCC or ground to prevent undefined states. Check absolute maximum ratings before applying voltages beyond specified limits.

Inverter Gates Selection Notes

Select this component for designs requiring standard CMOS logic with wide voltage flexibility. It offers significant power reduction compared to LSTTL logic ICs. Verify that input signal edge rates meet recommended transition times to avoid oscillations. Ensure output capacitive loads remain within specified limits for optimal performance.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must be terminated to either VCC or ground. They can be directly terminated or connected via pull-up/pull-down resistors to prevent floating states.

What is the recommended bypass capacitor value?

A 0.1-μF capacitor is recommended for each VCC terminal, placed physically close to the device to prevent power disturbances.
