NEXPERIA 74HCT14D Hex Schmitt Inverter Trigger, SOIC-14 Pin

The NEXPERIA 74HCT14D is a high-speed hex inverting Schmitt trigger integrated circuit (IC) supplied in a compact 14-pin SOIC (Small Outline Integrated Circuit) package. This advanced Si-gate CMOS device is engineered to be directly pin-compatible with Low-Power Schottky TTL (LSTTL) logic families, offering a versatile upgrade path for existing designs while maintaining signal integrity.

Its core function is to provide six independent inverting buffers, each equipped with Schmitt trigger action. This specialised input circuitry is crucial for conditioning noisy or slowly changing input signals, transforming them into clean, sharply defined, and jitter-free digital output signals. This makes it an indispensable component for ensuring reliable operation in digital systems where signal integrity is paramount.

Key Features & Applications

Typical applications for the 74HCT14D are extensive within electronic circuit design. It is commonly employed as a wave and pulse shaper, cleaning up analogue sensor outputs or clock signals. It is also ideal for constructing timing circuits such as astable multivibrators (oscillators) and monostable multivibrators (one-shot timers), thanks to its precise switching characteristics. The device operates from a wide supply voltage range of 2V to 6V, providing design flexibility, while maintaining low power dissipation for energy-efficient operation. Built-in ESD protection enhances its robustness during handling and assembly.

Specifications & Compliance

Specified in compliance with JEDEC standard number 7A, the 74HCT14D guarantees reliable performance and interoperability. It is designed to operate over a broad ambient temperature range from -40°C to +125°C, making it suitable for industrial, automotive, and commercial applications. With an output current capability of 4mA, it can drive standard logic inputs and small loads directly. This IC combines
