SN74HC14DBR TI Schmitt-Trigger Inverter | 14-SSOP | 6 Channels, 2V-6V

Product Overview

The SN74HC14DBR from Texas Instruments is a hex Schmitt-trigger inverter IC designed for high-speed, low-power digital logic applications. It features six independent inverters with Schmitt-trigger inputs, providing hysteresis for noise immunity and clean signal shaping. Housed in a compact 14-SSOP package, this device operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial systems. The SN74HC14DBR is ideal for wave shaping, pulse conditioning, and interface circuits where slow or noisy input signals need to be converted into clean digital outputs.
