SN74HC11DBR

Inverter Gates Overview

The SN74HC11DBR is a Texas Instruments logic gate 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 standard high-impedance CMOS inputs with clamp diodes. It supports fanout up to 10 LSTTL loads while offering significant power reduction compared to LSTTL logic ICs.

Inverter Gates Feature Summary

• Contains three independent 3-input AND gates performing the Boolean function Y = A ● B ● C
• Features buffered inputs and balanced CMOS push-pull outputs for similar sourcing and sinking currents
• Includes positive and negative clamping diodes on all inputs and outputs

Inverter Gates Applications

• Combining power good signals
• Enabling digital signals
• Directly controlling motor controller reset pins by combining multiple input signals

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC (14) package with tape-and-reel carrier. Confirm RoHS compliance and lead finish details in the latest Package Option Addendum. Ensure the component status is Active rather than Obsolete before procurement.

Inverter Gates Selection Notes

Select this component when three independent 3-input AND functions are required in a single package. It is suitable for designs needing wide voltage operation between 2 V and 6 V. Consider its balanced output drive capability and low power consumption relative to LSTTL alternatives.

Inverter Gates Part Context

This part belongs to the SNx4HC11 family of Triple 3-Input AND Gates manufactured by Texas Instruments. The HC series utilizes CMOS technology to provide high-speed performance with low power dissipation. The device is designed for general-purpose digital logic applications requiring reliable signal combination.

Inverter Gates Replacement Considerations

SN74HC11DR: Same manufacturer, same logic function, same SOIC-14 package, but different carrier type (Tube vs Tape & Reel).

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using pull-up or pull-down resistors to prevent undefined operational states.

What is the maximum recommended capacitive load?

To ensure optimal performance, the capacitive load at the output should be less than or equal to 70 pF.
