SN74HC11N

Inverter Gates Overview

The SN74HC11N is a triple 3-input AND gate manufactured by Texas Instruments in the HC logic family. 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 features buffered inputs, balanced CMOS push-pull outputs, and standard high-impedance CMOS input characteristics. It provides significant power reduction compared to LSTTL logic ICs and supports fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

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

Inverter Gates Applications

• Combining power good signals
• Enabling digital signals
• Directly controlling reset pins requiring multiple active-high conditions

Inverter Gates Procurement Notes

Verify the specific package type and lead finish against the orderable addendum. Confirm RoHS compliance status and ensure the selected variant matches the required thermal and electrical specifications for the intended application environment.

Inverter Gates Selection Notes

Select this component when a triple 3-input AND function is required in a single package. Ensure the design accommodates the wide operating voltage range and verify that unused inputs are properly terminated to prevent undefined operational states or excessive current consumption.

Inverter Gates Part Context

This part belongs to the SNx4HC11 series of triple 3-input AND gates. It is available in various packages including SOIC, PDIP, SOP, TSSOP, CDIP, and CFP. The SN74HC11N specifically denotes the PDIP (Plastic Dual In-line Package) variant suitable for through-hole mounting.

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 oscillations and undefined operational states.

What is the recommended bypass capacitor value?

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