Product Overview: 74VHC14D from NXP

The 74VHC14D is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is fabricated using silicon gate CMOS technology which provides the inherent benefits of CMOS - low quiescent power and high noise immunity. The 74VHC14D is a hex inverter featuring Schmitt-trigger action at each input, which makes it particularly suitable for transforming slowly changing input signals into sharply defined, jitter-free output signals, thereby enhancing noise immunity.

Key Features:

• Hex Inverter Design: The device contains six independent inverters, providing multiple buffering options within a single package.
• Schmitt-Trigger Inputs: These inputs provide hysteresis which is essential for transforming noisy or slow input signals into clean digital output signals.
• High Noise Immunity: The VHC technology ensures a high degree of noise immunity, which is critical for stable operation in electrically noisy environments.
• Low Power Consumption: CMOS technology delivers low power dissipation, making the 74VHC14D suitable for battery-operated and power-sensitive applications.
• Wide Operating Voltage: The device supports a broad range of operating voltages from 2.0V to 5.5V, accommodating various system level power requirements.
• Fast Propagation Delay: With its fast switching characteristics, the device is designed for high-speed applications.
• Output Drive Capability: The 74VHC14D can drive up to 8 LSTTL loads, providing ample output current for most applications.
