CD74HC14PW Description

The CD74HC14PW from Texas Instruments is a high-speed CMOS hex Schmitt-trigger inverter housed in a 14-pin TSSOP package. Designed for surface-mount applications, it operates within a 2V to 6V supply voltage range, making it compatible with a wide array of digital systems. This device features six independent inverters, each with Schmitt-trigger inputs for improved noise immunity and signal conditioning. With a maximum propagation delay of 23ns at 6V and 50pF load, it ensures reliable performance in high-speed logic applications. The low quiescent current (2 µA max) and RoHS3 compliance further enhance its suitability for modern, energy-efficient designs.

CD74HC14PW Features

• Schmitt-Trigger Inputs: Provides hysteresis (1.5V to 4.2V for high-level, 0.3V to 1.2V for low-level), ensuring robust noise rejection and clean signal transitions.
• Wide Voltage Range (2V–6V): Supports compatibility with TTL and CMOS logic levels.
• High Output Drive (5.2mA sink/source): Capable of driving moderate loads directly.
• Low Power Consumption: Quiescent current of just 2 µA maximizes energy efficiency.
• Fast Switching (23ns max delay): Ideal for timing-critical applications.
• Surface-Mount Package (TSSOP-14): Compact footprint for space-constrained PCB designs.
• Industrial-Grade Reliability: REACH unaffected and MSL 1 (unlimited) rated for extended shelf life.

CD74HC14PW Applications

• Signal Conditioning: Cleans up noisy signals in sensor interfaces or communication systems.
• Oscillators & Pulse Shaping: Used in RC-based timing circuits due to Schmitt-trigger hysteresis.
• Debouncing Switches: Eliminates contact bounce in mechanical switches/keypads.
• Level Translation: Bridges logic levels between 3.3V and 5V systems.
• Industrial Control Systems: Reliable operation in electrically noisy environments.

Conclusion of CD74HC14PW

The CD74HC14PW stands out as a versatile, high-performance inverter IC, combining Schmitt-trigger robustness with low-power CMOS efficiency. Its wide voltage range, fast response, and compact packaging make it ideal for applications demanding noise immunity and signal integrity, from consumer electronics to industrial automation. Texas Instruments' adherence to RoHS3 and REACH standards ensures environmental compliance, while the TSSOP-14 package optimizes board space. For designers seeking a reliable, high-speed logic solution, the CD74HC14PW delivers exceptional value.
