SN74HC11D

Inverter Gates Overview

The SN74HC11D is a Texas Instruments integrated circuit containing three independent 3-input AND gates. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device provides buffered inputs, balanced CMOS push-pull outputs, and ESD protection exceeding 2000 V (HBM). It is housed in a 14-pin SOIC package.

Inverter Gates Feature Summary

• Contains three independent 3-input AND gates performing the Boolean function Y = A ● B ● C
• Features buffered inputs and standard CMOS input levels with high impedance characteristics
• Provides balanced CMOS push-pull outputs capable of sinking and sourcing similar currents

Inverter Gates Applications

• Combining power good signals
• Enabling digital signals
• Directly controlling RESET pins of motor controllers requiring multiple active-high conditions

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum. Confirm that the 'D' suffix corresponds to the SOIC package variant. Check the production status field for availability, as some variants may be marked obsolete while others remain active. Ensure compliance with RoHS requirements and lead finish specifications listed in the orderable information.

Inverter Gates Selection Notes

Select this component when a triple 3-input AND logic function is required in a compact surface-mount format. Verify that the system supply voltage falls between 2 V and 6 V. Ensure input signal edge rates meet recommended transition times to prevent oscillations. Consider thermal resistance metrics if operating near maximum junction temperatures or driving significant capacitive loads.

Inverter Gates Part Context

This device belongs to the SNx4HC11 family of Triple 3-Input AND Gates manufactured by Texas Instruments. It is part of the broader HC (High-speed CMOS) logic series, designed to offer performance improvements over older logic families while maintaining pin compatibility with Low-power Schottky TTL (LSTTL) standards.

Inverter Gates Replacement Considerations

SN74HC11DR: Same functional logic and electrical characteristics but supplied in tape-and-reel packaging instead of tube.
