MC74AC14DTR2G

MC74AC14DTR2G Description

The MC74AC14DTR2G from onsemi is a high-performance hex Schmitt-trigger inverter belonging to the 74AC series. Packaged in a 14-pin TSSOP with tape-and-reel (TR) mounting, this surface-mount device (SMD) is designed for 2V to 6V operation, making it suitable for both 3.3V and 5V logic systems. It features six independent inverters with Schmitt-trigger inputs, ensuring robust noise immunity and hysteresis for clean signal conditioning. With a maximum propagation delay of 10ns at 5V/50pF, it delivers high-speed performance while maintaining low power consumption (4µA quiescent current). Its 24mA output drive capability supports moderate load requirements, and its RoHS3 compliance ensures environmental safety.

MC74AC14DTR2G Features

• Schmitt-Trigger Inputs: Provides hysteresis (typically 0.9V), enhancing noise rejection and signal integrity in noisy environments.
• Wide Voltage Range (2V–6V): Compatible with TTL and CMOS logic levels, offering flexibility in mixed-voltage designs.
• High-Speed Operation: 10ns propagation delay at 5V, ideal for timing-critical applications.
• Low Power Consumption: 4µA max quiescent current minimizes energy usage in battery-powered systems.
• Strong Output Drive: 24mA sink/source current ensures reliable interfacing with LEDs, relays, or other peripherals.
• Robust Packaging: TSSOP-14 with tape-and-reel for automated assembly, MSL 1 (unlimited) for moisture resistance.

MC74AC14DTR2G Applications

This IC excels in applications requiring signal conditioning, debouncing, or waveform shaping, such as:

• Switch Debouncing: Cleans mechanical switch inputs in industrial controls or consumer electronics.
• Clock Signal Conditioning: Stabilizes oscillators or clock edges in microcontrollers and FPGAs.
