SN74HC14DBR

Inverter Gates Overview

The SN74HC14DBR is a hex inverter with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -40°C to +85°C. The device features buffered inputs, balanced CMOS push-pull outputs, and clamp diode structures on all pins. It provides significant power reduction compared to LSTTL logic ICs and supports fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for noise tolerance
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Buffered inputs improve signal integrity
• Clamp diodes protect against input and output overvoltage

Inverter Gates Applications

• Synchronize inverted clock inputs
• Debounce a switch
• Invert a digital signal

Inverter Gates Procurement Notes

Verify the package type matches the design requirements, as the SN74HC14 series is available in multiple packages including SOIC, SSOP, PDIP, SOP, TSSOP, CDIP, CFP, and LCCC. Confirm that the specific ordering suffix corresponds to the desired packaging format and ensure compliance with RoHS standards if required by the application specifications.

Inverter Gates Selection Notes

Select this component when slow or noisy input signals require Schmitt-trigger filtering. Ensure the supply voltage remains between 2V and 6V. Consider thermal resistance values for the specific package variant during high-frequency operation. Unused inputs must be terminated to VCC or GND to prevent undefined operational states.

Inverter Gates Part Context

This part belongs to the SNx4HC14 family of hex inverters with Schmitt-trigger inputs. It is designed for general-purpose digital logic applications requiring signal inversion and noise immunity. The device performs the Boolean function Y = A in positive logic across six independent channels.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must be terminated at VCC or GND to prevent undefined operational states caused by floating voltages.

What is the maximum capacitive load recommended?

It is recommended to keep the total capacitive load at the output less than or equal to 70 pF to ensure optimal performance.
