SN74HC11DBRE4

Inverter Gates Overview

The SN74HC11DBRE4 is a triple 3-input AND gate manufactured by Texas Instruments. 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 inputs with internal clamp diodes. 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 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

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the package type matches the required SOIC (D) footprint dimensions of 8.70 mm x 3.90 mm for PCB layout compatibility.

Inverter Gates Selection Notes

Select this component when a triple 3-input AND function is required in a compact surface-mount package. It is suitable for designs needing wide voltage operation between 2 V and 6 V. Consider its standard CMOS input characteristics, which require fast edge rates to prevent oscillations, rather than Schmitt-trigger inputs.

Inverter Gates Part Context

This part belongs to the SNx4HC11 family of Triple 3-Input AND Gates. It is pin-compatible with Low-power Schottky TTL (LSTTL) devices but offers significantly lower power consumption. The device is designed for general-purpose digital logic applications requiring reliable signal combining and enabling functions.

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 are the requirements for input signal edge rates?

The SN74HC11 has standard CMOS inputs that cannot tolerate slow edge rates. Slow transitions can cause excessive current consumption and oscillations; fast edge rates as defined in the Recommended Operating Conditions must be maintained.
