SN74AC14N Description

The SN74AC14N from Texas Instruments is a hex Schmitt-trigger inverter integrated circuit (IC) designed for high-performance logic applications. Housed in a 14-pin DIP (Dual Inline Package), this device features six independent inverters with Schmitt-trigger inputs, ensuring robust noise immunity and signal conditioning. Operating within a 2V to 6V supply range, it delivers low power consumption (max 2 µA quiescent current) and high-speed performance, with a maximum propagation delay of 10ns at 5V with a 50pF load. Its ROHS3 compliance and REACH-unaffected status make it suitable for environmentally conscious designs.

SN74AC14N Features

• Schmitt-Trigger Inputs: Provides hysteresis (input thresholds: 0.5V–1.1V for LOW, 2.2V–3.9V for HIGH), enhancing noise rejection and signal integrity.
• High Drive Capability: Supports 24mA output current (sink/source), enabling direct interfacing with LEDs, relays, and other peripherals.
• Wide Voltage Range (2V–6V): Compatible with 3.3V and 5V systems, offering design flexibility.
• Low Power Consumption: 2 µA max quiescent current ensures energy efficiency.
• Through-Hole Mounting (DIP): Simplifies prototyping and breadboard use.
• Industrial-Grade Reliability: 74AC series ensures robust performance in harsh environments.

SN74AC14N Applications

• Signal Conditioning: Ideal for debouncing switches and squaring noisy waveforms in sensor interfaces.
• Clock Signal Shaping: Used in oscillator circuits to clean up distorted clock signals.
• Logic Level Translation: Bridges 3.3V and 5V systems due to its wide voltage range.
• Pulse Generation: Employed in monostable multivibrators for timing applications.
• Industrial Control Systems: Suitable for PLC I/O modules where noise immunity is critical.

Conclusion of SN74AC14N

The SN74AC14N stands out for its Schmitt-trigger hysteresis, high noise immunity, and versatile voltage range, making it a preferred choice for signal integrity-critical designs. Its high drive strength, low power consumption, and through-hole packaging cater to both prototyping and industrial applications.
