SN74HC14N TI Hex Schmitt-Trigger Inverter DIP-14 Pack of 5 Low Power

Description

Product Overview

The SN74HC14N is a high‑performance hex Schmitt‑trigger inverter manufactured by Texas Instruments, presented in a convenient DIP‑14 package that fits easily onto standard breadboards and prototype boards. Each device contains six independent inverters, each equipped with a Schmitt‑trigger input that provides hysteresis, reducing noise susceptibility and ensuring clean digital transitions. The part operates over a wide supply voltage range of 2 V to 6 V, making it suitable for both low‑voltage microcontroller environments and higher‑voltage logic families.

Designed for low power applications, the IC draws a maximum supply current of only 20 µA (ICC) and an input leakage current of just 1 µA, which helps extend battery life in portable designs. Despite its low power profile, the SN74HC14N can source or sink up to ±4 mA at a 5 V supply, allowing it to drive up to ten LSTTL loads per output. The typical propagation delay is 11 ns, delivering fast response times that are essential for high‑speed digital circuits.

Each inverter channel is protected against over‑voltage conditions and includes built‑in ESD protection, contributing to the overall reliability of the component in demanding industrial and scientific applications. The device’s robust construction and consistent performance have earned it a strong reputation among engineers who require dependable logic conversion in compact form factors.

Usage

The SN74HC14N finds use in a broad spectrum of electronic projects and professional designs. Its Schmitt‑trigger inputs make it ideal for cleaning up noisy signals from mechanical switches, sensors, and low‑level analog sources before they enter digital logic. Engineers often employ the device in edge‑detect circuits, pulse‑stretching applications, and as part of oscillator or timing circuits where precise threshold control is required.

Because of its wide operating voltage range, the IC can be integrated into battery‑powered devices, handheld instrumentation, and low‑power IoT modules. The ability to drive multiple LSTTL loads means it can serve as an interface between modern CMOS logic and legacy TTL systems, facilitating seamless communication across different technology generations.

In educational settings, the DIP‑14 footprint simplifies hands‑on learning for students exploring digital logic fundamentals. The six independent inverters allow multiple experiments to be conducted on a single chip, reducing component inventory and cost for teaching labs.
