STMicroelectronics 74VHC14TTR Hex Schmitt Inverter

The 74VHC14TTR from STMicroelectronics is a high-speed Si-gate CMOS device that is designed to offer robust performance in a wide range of applications. This device comprises six independent inverters with Schmitt-trigger inputs, which are specifically designed to transform slowly changing input signals into sharply defined, jitter-free output signals, making it ideal for applications that require wave-shaping or noise filtering.

Each inverter in the 74VHC14TTR is capable of transforming an input signal into a complementary output signal with a high degree of precision. The Schmitt-trigger action at the input of each gate provides a hysteresis voltage which enhances noise immunity and transforms a slowly changing input signal to a fast changing, jitter-free output. This feature is particularly useful in environments with high electrical noise or when signals are transmitted over long distances.

The device operates over a wide power supply range of 2V to 5.5V, making it suitable for use in systems that require low power consumption. The low power supply voltage range also allows for compatibility with most TTL levels, ensuring easy integration into a variety of digital circuits.

With its fast propagation delay and high noise immunity, the 74VHC14TTR is an excellent choice for use in wave and pulse shapers, astable multivibrators, monostable multivibrators, and in any application that requires high-speed, reliable logic inversion with noise filtering capabilities. It's packaged in a TSSOP14 package, which is optimized for minimal space and weight in high-density circuit designs.

Key features of the 74VHC14TTR include:

• High noise immunity characteristic of CMOS devices
