SN74ACT14N

SN74ACT14N Description

The SN74ACT14N from Texas Instruments is a hex Schmitt-trigger inverter IC designed for high-speed logic applications. Housed in a 14-pin DIP (Through Hole) package, it features six independent inverters with Schmitt-trigger inputs, ensuring robust noise immunity and signal conditioning. Operating within a 4.5V to 5.5V supply range, it delivers a maximum propagation delay of 11.5ns at 5V with a 50pF load, making it suitable for high-performance digital systems. The device is ROHS3 compliant and adheres to REACH and EAR99 regulations, ensuring environmental and export compliance.

SN74ACT14N Features

• Schmitt-Trigger Inputs: Provides hysteresis (typically 0.5V to 1.4V for LOW and 1.2V to 2.1V for HIGH), enhancing noise rejection and signal integrity.
• High-Speed Operation: 11.5ns propagation delay at 5V, ideal for timing-critical applications.
• Balanced Output Drive: 24mA sink/source current ensures strong output capability for driving capacitive loads.
• Low Power Consumption: Quiescent current of just 2µA (max), reducing overall system power draw.
• Wide Operating Voltage: Supports 4.5V to 5.5V, compatible with TTL and CMOS logic levels.
• Robust Packaging: Through-hole DIP for easy prototyping and repair in industrial environments.

SN74ACT14N Applications

• Signal Conditioning: Cleans up noisy signals in sensor interfaces or communication systems.
• Pulse Shaping: Converts slow or distorted waveforms into crisp digital signals for clocks or timing circuits.
• Debouncing Circuits: Eliminates contact bounce in mechanical switches (e.g., keyboards, relays).
• Oscillators: Forms RC or crystal-based oscillators due to Schmitt-trigger hysteresis.
• Industrial Control Systems: Used in PLCs and motor drives where noise immunity is critical.

Conclusion of SN74ACT14N

The SN74ACT14N excels in high-speed, noise-immune logic inversion, combining Schmitt-trigger reliability with low power consumption and strong output drive.
