Product Introduction

Overview

The SN74AC14PWR, produced by Texas Instruments, is a hex Schmitt-trigger inverter integrated circuit. This device is part of the 74AC series, known for its high-speed CMOS logic. It features six independent inverter circuits, each with Schmitt-trigger inputs, which provide hysteresis to improve noise immunity and prevent multiple transitions on slow input signals.

The SN74AC14PWR operates over a wide voltage range of 2V to 6V, making it versatile for various applications. It is particularly useful in scenarios where clean, jitter-free output signals are required, even from slow input ramps.

Key Features

  • VCC Operation Range: The device operates over a voltage range of 2V to 6V, allowing for flexibility in different system designs.
  • Schmitt-Trigger Inputs: Provides hysteresis to improve noise immunity and prevent multiple transitions on slow input signals.
  • Temperature Compensated: Ensures stable operation over a wide temperature range.
  • Balanced CMOS Push-Pull Outputs: Capable of sinking and sourcing similar currents, reducing output ringing and overshoot.
  • Input Voltage Tolerance: Inputs can accept voltages up to 6V, making it suitable for voltage translation applications.
  • Low Drive and Slow Edge Rates: Minimizes output ringing and overshoot, ideal for bus interface applications.

Applications

  • Synchronize Inverted Clock Inputs: Useful in clock signal synchronization to ensure clean and stable clock signals.
  • Debounce Switches: The Schmitt-trigger action helps in debouncing switches by filtering out noise and providing a clean output signal.
  • Invert Digital Signals: Can be used to invert digital signals in various digital circuits.
  • Bus Interface Applications: Ideal for applications where output ringing is a concern, such as in D-Type flip-flops, counters, and other digital logic circuits.
